PiRate Ratings For NFL Football: Week 5–October 10-11, 2010

Four weeks into the NFL season gives us enough time to begin to make assumptions.  There just may not be a great team in the league this year.  The Kansas City Chiefs are the only undefeated team left, and it is a good bet they will not be so after this week.

We have a lot of mediocre teams and a handful of good but not great teams.  Scoring is down this year.  That gives the odds makers quite a dilemma.  The underdog is covering more than ever this year.  The lines will be shorter, and this will create many instances where sweetheart teaser plays become more advantageous.

If a team that should be a five-point favorite all of a sudden becomes a two and a half-point favorite, then playing a 10-point teaser to make them a seven and a half-point underdog becomes truly sweet and playing a 13-point teaser to make them a 10 ½-point underdog becomes money in the bank.

The PiRates are having a great time playing these NFL sweetheart teasers so far this year.  In fact, we may have to consider not playing any college games and picking just NFL games, at least as long as this hot streak continues.

We have also fattened up on money line parlays that take advantage of the fact that favorites are still winning but not covering.  The lower the regular spread, the lower the money line odds.

PiRate Ratings For NFL Football: Week 2–September 19-20, 2010

18.3!  That is the average number of points scored per team in the opening week of the 2010 NFL season.  That is a little more than a field goal less per team compared to last year.  Is this a sign that scoring is about to become harder in the league, or is it more of a case of so many closely-matched contests in week one?  We will have to wait a couple of weeks before we can begin to make an assumption.

Week two finds a handful of interesting games on the slate.  The Jets hook up with the Pats, and it is almost a must-win game for Coach Rex Ryan and his crew.  After losing Monday night at home to Baltimore, a loss would to New England would give Team Belichick a two-game edge in the AFC East.

Indianapolis hosts the Giants in a battle of Manning vs. Manning.  The Colts could not stop the Houston running game, and the Texans are not a rushing behemoth.  If Eli and company get the best of Peyton and company, the Colts could be two games behind the rest of the division.

Kansas City visits Cleveland, and if the Chiefs can pull off the road win over a weak Browns’ team, they will become a legitimate threat in the AFC West.  The Chiefs get Cleveland and Buffalo as part of finishing fourth in the division last year, while the Chargers must play New England and Cincinnati. 

Dallas hosts Chicago, and the Cowboys must rebound or else they could find themselves in a hole they cannot crawl out of.  Jerry Jones might even begin to consider his options if the Cowboys lay another egg offensively this week.  The mental anguish of having the winning touchdown called back could do to Dallas what Virginia Tech’s loss to Boise State did to the Hokies.  Additionally, Chicago benefitted from a final play penalty to beat Detroit, and the Bears could get a positive bounce from that event.

The Saints and Vikings got an extra three days to prepare for their second games.  Minnesota hosts Miami.  The Dolphins struggled to beat the hapless Bills, and the Vikes are much better at home than they are on the road.  After the opening touchdown drive, Minnesota’s defense shut down Drew Brees.

The Saints fly into a hornet’s nest in San Francisco.  Mike Singletary will have the 49ers hopping mad after the embarrassing loss at Seattle.

Introducing the PiRate NFL Pass Rating Formula

 

The National Football League has been using the same pass rating formula for multiple decades.  It uses a combination of completion percentage, yards per attempt, touchdowns, and interceptions.  If you want to calculate it on your own, here it is:

 

I.     (Completion Percentage-30.0) * 0.05 +

II.    (Yards per attempt-3.0) * 0.25 +

III.   (20 * touchdowns per pass attempt) +

IV.   2.375 – (25 * interceptions per pass attempt)

 

If any of these four components are greater than 2.375, then cap the value at 2.375

 

Add these four stats together and multiple them by 16.667 to get the passer rating.  Here is an example:

 

In 1963, Y. A. Tittle had these stats for the New York Giants

Completions 221  Attempts 367  Yards 3145  Touchdowns 36  Interceptions 14

 

I.     (60.20 – 30.0) * 0.05 = 1.51  +

II.    (8.57-3.0) * 0.25 = 1.39        +

III.   (20 * .098) = 1.96                +

IV.   2.375 – (25 * .038) = 1.43    +

 

 Subtotal = 6.29     6.29 * 16.667 =

                     104.8

 

Once you know this formula, you can easily plug it into a spreadsheet and figure the ratings.  However, these ratings are a poor way to select the most efficient passer.

 

Let’s take a look at two opposing passers, Smith and Jones.

 

Smith completes 15 of 24 passes for 3 touchdowns with no interceptions.

 

Jones completes 10 of 24 passes for 0 touchdowns and 1 interception.

 

Smith is obviously much better, correct?  No, not correct.  It depends on several other things.  What if Jones has a lousy offensive line or receivers that drop every other pass thrown to them?  What if Smith has all day to pass with Jerry Rice-type receivers?  All these stats show us are just that—their stats.

 

Smith could have completed six passes to backs behind the line of scrimmage with the backs following blocking for long gains.  Jones could have threaded the needle with 30 yard passes to the deep sidelines only to have had them dropped by inept receivers.

 

In essence no pass-rating formula is worth a grain of salt.  Let’s look at two separate plays.  Passer A completes 13-yard pass for a touchdown.  It is a dump pass into the flat to the tailback with the tailback avoiding three defenders as he streaks into the end zone.  This one pass gets the NFL Maximum rating of 158.3.

 

Now, let’s look at Passer B.  His team is backed up at their own 1 yard line. He drops back and fires a bomb 55 yards through the air that comes down perfectly in the hands of his flanker.  The flanker takes off down the sideline and is knocked out just one yard from scoring.  This 98-yard pass gives Passer B a rating of 118.8!  Peyton Manning actually had a better total season rating than this a couple years ago, and even though he ranks among the best ever, he was not worth a 98-yard completion every time he threw the ball!

 

Can this be?  You betcha!  The rating is flawed.  Obviously the brilliantly thrown pass that travelled 55 yards past the line of scrimmage that comes down perfectly in the hands of the intended receiver should be worth a lot more than the dump pass that I could complete given two seconds protection.

 

Here is where the PiRate Pass Rating Formula tries to correct the incorrect values of the NFL Pass Rating Formula.

 

Our formula looks at just two statistics.  The first is interception percentage.  An intercepted pass is worth anywhere from 3 to 7 points for the other team on average.  We realize that all interceptions are not the same.  A poorly thrown pass into the flat at the offense’s 20-yard line hurts much more than a 3rd and 25 pass thrown 40 yards downfield and intercepted by the defense. 

 

The second stat is called “Air Yards Per Attempt,” or AYPA.  It is simply the passing yardage minus the yards after catch.  If Passer A completed a 51-yard pass for a touchdown, but the play consisted of a pass completed to a tailback one yard past the line of scrimmage with the back running for 50 yards, the passer gets credit for an AYPA of 1 yard (51 yard pass – 50 yards after the catch).

 

Here is the PiRate Pass Rating Formula:

[AYPA * 7 – (11 * Interception %) + 105] * 0.8

 Interception percentage is figured as: (Interceptions/Attempts) *100

 Anything over 100 is an excellent rating.  Over 90 means the QB is above average.  80 would be considered average; below 80 means this QB should be looking over his shoulder for a replacement to take his job.

 In our passer rating, we don’t include passing percentage or touchdown passes.  Yards gained are what matters.  Three consecutive completed passes that gain a total of nine yards means 4th & 1.  Two incomplete passes followed by an 11 yard completion means 1st & 10.  Which outcome is better?

 Touchdowns skew the ratings.  If one coach sends in passing plays at the opponents’ one yard line, while another sends his 240-pound power back to plunge over the goal, the quarterbacks will get too much credit in once instance and no credit in the other. 

 Let’s take a look at the PiRate Rating in action.  First, you must be wondering where can you find AYPA?  There is an excellent website that carries this stat, so you don’t have to try to figure out the YAC for each QB.  Go to: www.advancednflstats.com.

Coming tomorrow: We reveal the initial NFL PiRate, Mean, and Bias ratings for the 2010 season and give our predictions for each division.

AFC South Preview

AFC South Preview

 

With this preview, I will reveal the PiRate Ratings for each of the four teams in the AFC South Division.  Following those ratings are the Mean Ratings and my own biased opinion (last year’s final PiRate Rating combined with how much stronger or weaker I personally think each team is compared to last season).  That will give you three different ratings for the teams.

 

When all three ratings predict the same side to win a game against the spread, then that is a playable line.  If all three ratings agree on the winner of the game, and the Las Vegas Line is single digits, then that becomes a playable game on the Money line.  The reason for not playing any double digit spreads is that the Money line odds would be too prohibitive for a double digit favorite, where just one loss could result in a losing season.  During the season, I will also supply a list of games to be played with an imaginary bank account.

 

The predicted records are not tied to the PiRate or Mean Ratings; they are strictly from my biased ratings.

 

I expect 2008 to have a changing of the guard at the top of the division.  Indianapolis has dominated the South Division since its inception, and I believe Jacksonville is poised to take over the top spot this season.  The Colts should still easily make the playoffs as a wildcard, while the Titans and Texans beat up on teams outside the division and threaten to make this two straight years with no losing record in the division.

 

Houston Texans
PiRate	99.0
Mean	97.5
Biased	97.3
Run Offense	D
Pass Offense	B+
Run Defense	B-
Pass Defense	C
Special Teams	A
Predicted Record	7-9

Offense: Matt Schaub is a better than average quarterback, but he has never played a full 16 games in any season.  Backup Sage Rosenfels plays just as competently as Schaub, so there isn’t much difference in who plays under center.  The big problem is an anemic running game.  Ahman Green is well past his prime, and Chris Brown is an injury waiting to happen.  Look for the Texans to finish under 100 yards per game in the rushing department.  The receivers are competent but not fantastic.  Kevin Johnson and Andre Walter aren’t game-breakers, but they aren’t chopped liver either.  They will get open and catch passes, but don’t expect fancy yards per catch numbers.

 

Defense: The defense will progress as long as end Mario Williams continues to play like he did last year.  Williams proved worthy of his being the first pick in the 2005 draft when he recorded 14 sacks and proved to be almost as good against the run last year.  The secondary is a question, and lack of an adequate back line will prevent this team from taking a step forward. 

 

Special Teams: When you have a player who returned three kicks for touchdowns the year before, you have to take notice.  Andre Davis cannot possibly repeat that feat again this year, but he is likely to force opponents to alter their regular kickoff strategy.  That will give the Texans good starting field position.  Kicker Kris Brown has a strong and accurate leg, and he can win a game with a 55-yard field goal.  Punter Matt Turk is more effective due to an outstanding coverage team

 

Summary: Houston may take a small step backward this year.  With little running game support, teams will sell out and go hard at the Texan quarterbacks.  It won’t be a return to the David Carr days, but it will mean a losing record.

 

Indianapolis Colts
PiRate	110.9
Mean	106.7
Biased	102.6
Run Offense	B
Pass Offense	A
Run Defense	B
Pass Defense	B
Special Teams	C
Predicted Record	10-6

Offense: Peyton Manning is still one of the best quarterbacks of all time, but this will be a down year for him.  Never much of a scrambler, he will be even less mobile this year on the heels of minor surgery to repair an infected bursa sac in his left knee.  Throw in the fact that his center for most of his time in the NFL, Jeff Saturday, is out with an MCL injury to his knee, and the Colts actually have an offensive liability of sorts this year.  While Indy won’t all of a sudden look like the Chiefs, this offense will score fewer points this season than it has in many years.  Look for a drop down to about 385 points.

 

Defense: The Colts’ defense is usually overlooked due to the powerful offense, but this year, the stop troops may be forced to dominate to win a couple of those tough games against playoff-quality opponents.  There is a concern at the beginning of the year with the defensive line, as three starters (tackle Raheem Brock and ends Robert Mathis and Dwight Freeney) begin the season with injuries in their legs.  The secondary is terrific, but they may have to defend a bit longer on passing plays this year if the pass rush fails to get to the quarterback.

 

Special Teams: The Colts are not strong here.  Kicker Adam Vinateri suffered through his worst season last year, failing to make even one field goal of 40 yards or more.  Whether that was an aberration or a sign of decline is still to be determined.  Punter Hunter Smith is run-of-the-mill.  T.J. Rushing has the potential to be a game-breaker in the return games.

 

Summary: Many teams would be ecstatic with a 10-6 record, but if the Colts fall to this mark, it will be a disappointment.  After many years of 12, 13, or 14 wins, I see Indianapolis dropping to 10-6 and having to play as a wildcard in the playoffs.

 

Jacksonville Jaguars
PiRate	108.8
Mean	105.6
Biased	103.3
Run Offense	A-
Pass Offense	B
Run Defense	B
Pass Defense	B
Special Teams	B+
Predicted Record	11-5

Offense: David Garrard is an underrated passer who will start to get more recognition this season.  Garrard plays intelligently, never forcing a pass when another option is available.  He may not put up the numbers that Brady, Romo, or Peyton Manning puts up, but he gets the job done.  Jacksonville should top 400 points for the second year in a row.  There are some troubles in the receiving corps at the beginning of the season with injuries to Jerry Porter and Reggie Williams, but once they are healthy, this will be a solid but not spectacular group.  The running game should be stable and consistent with quality depth.  Fred Taylor will top 1,000 yards again if he stays healthy, while backup Maurice Jones-Drew has the potential to gain 1,000 yards if he gets more touches.

 

Defense: The Jaguars will be considerably better defensively this year, and that is why they have a shot at the Super Bowl.  I expect the stop troops to respond positively to new coordinator Gregg Williams and his pressure defense.  A healthier John Henderson will team with ends Paul Spicer and Reggie Hayward to make a formidable front line.  The second line of defense is top-rate, and the trio should thrive in the new system.  If middle linebacker Mike Peterson can play a full 16 games, the Jags could win 12 or even 13 games.  Jacksonville has a pair of fine cornerbacks leading the secondary.  Rashean Mathis and Brian Williams force passes away from their area.

 

Special Teams: This isn’t necessarily a strong unit, but they won’t lose games for the team either.  Kicker Josh Scobee is more-than-adequate but not among the league’s elite.  Punter Adam Podlesh is good at pooch punting the ball inside the opponents’ 20 yard line, but I expect he will have fewer chances to do so this year.  Jones-Drew will cause opposing kickoff coverages to fret.

 

Summary: The Jags may repeat with an 11-5 record this year, but I expect 11 wins to be good enough to win the division.  Additionally, this team may be better equipped to handle the playoffs.  While San Diego and New England will be favored over them, the Jags are a challenger for AFC supremacy this year.

 

Tennessee Titans
PiRate	99.4
Mean	99.5
Biased	98.6
Run Offense	B
Pass Offense	C-
Run Defense	B
Pass Defense	B
Special Teams	B-
Predicted Record	7-9

Offense: This is a team of ifs.  If Vince Young can become another version of Donovan McNabb rather than Bobby Douglass, the Titans have a chance to go places.  However, it’s a big if.  In the preseason, Young failed to lead the first team on any touchdown drives in the four games.  His passes were off target with regularity.  The next if is with the running game.  If rookie Chris Johnson proves to be a breakaway back and can supplement the power running of LenDale White, the Titans can set up the pass with their running game, especially if Young can take off on some long scrambles.  The receiving corps is nothing special, but Alge Crumpler, Justin Gage, and Justin McCareins will get open in the short to medium routes.

 

Defense: One player can make a difference, and it showed just how the Titans relied on him last year.  With tackle Albert Haynesworth in the lineup, Tennessee went 10-3 last year.  Without him, they were 0-3 and allowed double the amount of rushing yardage per game.  Jevon Kearse returns to his original team replacing Antwan Odom.  The linebacking unit features Keith Bulluck, one of the more underrated players in the league.  The secondary is good but not great.  Michael Griffin has the potential to be an all-pro safety, but he has to learn to play in control.

 

Special Teams: Kicker Rob Bironas was the top offensive weapon in 2007, and he enters the 2008 season with an injured groin.  Punter Craig Hentrich is starting to show signs of age, but he is still serviceable.  The Titans missed Pacman Jones last year (at least on the field), and they are looking for new blood to infuse their return game.

 

Summary: With two solid teams in the same division and an up and coming rival in their former city, the Titans are not going to repeat as an AFC Wildcard team this year.  Tennessee will struggle to reach .500 this season.  Young must step up and become a passing threat this year, or this team is headed for some rough times in the years ahead.
