NFL By the Numbers - Toxic Differential


NFL BY THE NUMBERS
Toxic Differential

We have entered the age of the sports nerd when it comes to stats.  No longer can we identify trends and predict success (usually after the fact) from mere mortal stats like yards allowed, average yards per pass, etc.  Now we seem to have a cottage industry that seeks to create and legitimize ever more nuanced
number breakdowns.  Blame it on Nate Silver. 



 I am a CPA by trade -- I love numbers and I love stats and I love trying to make sense of them.  But let's remember -- sometimes we only see in numbers what we want to see in them.
A word of caution as I introduce you to the Toxic Differential.

Brian Billack wrote a column today for Fox Sports that explains the Toxic Differential.  It is actually a pretty simple statistical analysis that combines two differentials:  Turnover margin and Big Play margin.  For this purpose a Big Play is a play that gains 20 or more yards.  

As an example consider the following data points for Mythical Team A:

Turnovers -              12 
Turnovers forced-      9

Big Plays -                 40 
Big Plays allowed      31

Team A therefore has a Toxic differential of 6 (-3 on turnovers and +9 on Big plays).  

An interesting stat --- but how well does it predict success on the field?   Niners, Ravens and Broncos are at the top of the list, that makes sense.  The Chiefs and Eagles are at the bottom of the list - that makes sense. (See chart below excerpted from Billack's article)  But....

How much predictive value of success is there to a stat where the Panthers, Browns, Lions and Redskins comprise half of the top eight (combined record 15-29)?  What should I make of the fact that the only two 10-1 teams in the NFL do not even crack the top ten (Houston is # 11, Atlanta #14)?

Coach Billack tries to draw some pained lessons from these stats - but it rings kind of hollow.  Simply put, Carolina's 3-8 record does not appear to jive with its fourth rated Toxic Differential.  This is a fun stat -- but so is picking winners by which jerseys you like best.  

The best stats are sometimes the most simple and require the fewest qualifications.  Look back at my November 8, 2012 post on sacks.  Teams that win the Super Bowl average 23% more sacks than the league as a whole.  Simple. Predictive.  Toxic Differential -- it tells me I should be expecting a Panthers/Browns throwdown in February before I should expect a Falcons/Texans contest.  Hmmm.

NFL Card Show - Bob Jeter


NFL CARD SHOW 

Bob Jeter
Writing my blog got me thinking about my roots as a fan of the NFL.  The first game I remember vividly was Super Bowl III played in 1969 between the Baltimore Colts of the NFL and the New York Jets of the AFL.   At about that same time I began to amass my football card collection.  I probably collected cards from grade one through grade seven.  Topps was the only card company at that time.  The cards came with the obligatory piece of cardboard style bubble gum.  

I am going to make each Wednesday show and tell for a card or two that I pull at random from my collection.  I hope you enjoy a trip down memory lane if this was your era, or a little history lesson if these cards are 10-20 
years older than you are.

The packers drafted Jeter in the second round of the 1960 draft. Jeter initially elected to play in the Canadian Football League, but came to his sense and joined the Packers in 1963.  Jeter was a fixture in the defensive backfield for the Packers for eight seasons.  He finished his career playing  three years with the hated Bears (1971-1973).

Jeter finished his career with 26 interceptions.  He made the All Pro team twice (1967, 1970)

Jeter played on three championship teams with the Packers (1965-1967).  The 1966 team won the first Super Bowl defeating the Kansas Chiefs 35-10.  The Packers defeated the Oakland Raiders in Super Bowl II 33-14.  Jeter played in the shadows of more famous Packer teammates.  He was however, a key cog in the  1960's Packer machine.

NFL Recap - Week Twelve


NFL RECAP – WEEK TWELVE


STATE OF THE GAME
For all the "any given Sunday" rhetoric (and I have been one of those using such rhetoric) regarding parity in the NFL, I can't remember a season where there has been less across the board suspense in the divisional races.  Let's take a look:

AFC East - The Patriots are the only team over 500 and have a three-game lead with five to play. 

AFC North - The Ravens have a three game lead over both the Bengals and the Steelers.  These three teams each have a game left with the other two.  That likely means they beat up on each other a little and nobody makes up or loses any ground. 

AFC South - The Texans have a three game lead over the surprising Colts and they will stay sharp until they secure home field for the playoffs. 

AFC West - The Broncos are the only team over 500 and own a four game lead with five games to play.  Since the Broncos have already defeated the 4-7 Chargers twice, they need simply to win one more game (or have the Chargers and Raiders each lose one more game) to clinch the division. 

NFC West - Niners with a 2.5 game lead over the Hawks and a head-to head victory over Seattle.  The Hawks can't win on the road so this race is over.

NFC East - Giants with a two-game lead over Washington and Dallas.  The race could get interesting if Washington beats New York at home this week - but I don't think that will happen.

NFC South - Falcons have a four game lead over the Bucs and are a lock to clinch the crown.

NFC North - The one legitimate race with the flawed 8-3 Bears leading the flawed 7-4 Packers by one game and the flawed 6-5 Vikings by two games.  As with their cousins in the AFC North - each of these three teams still has one game left against the other two.
  

5-10 MUSINGS FROM THE GAMES

In the NFC - Three
After this week's games I am of the opinion that there are only three teams in the NFC that have a realistic shot to represent the conference in the Super Bowl.  Those three teams are Atlanta, New York, and San Francisco.  My reasoning:  The other three teams will be a long shot wildcard, Green Bay, and Chicago.  Dallas, Seattle, Tampa Bay and Minnesota would not be capable of winning three road games in the playoffs if they secured the last wildcard spot.  Both Green Bay and Chicago would have to likely beat one or both of New York and San Francisco to reach the Super Bowl.  I don't think either of these teams can protect their quarterbacks consistently against the superior pass rushes the Giants and Niners possess.

In the AFC - Three
I am also of the opinion that only three teams in the AFC have a chance to represent the conference in the Super Bowl.  Those three teams are Houston, New England, and Denver.  My rationale is as follows.  First, neither of the two wild cards from the AFC will pose a realistic threat.  The two wild cards will likely come from the trio of the Bengals, Steelers, and Colts.  Each of those teams has the ability to pull off an upset and win one game in the playoffs, but I don't see any of them pulling off three road upsets.

The Ravens, Patriots and Broncos will likely slug it out for the second seed.  The Ravens hold a game lead over the Broncos and the Patriots and have already beaten the Patriots and play the Broncos in week 15.  The Patriots have defeated the Broncos and appear to have the easiest remaining schedule of the three. If the Broncos beat the Ravens it will be quite a scramble for the second seed.

 I think that the Broncos and the Patriots are more balanced and dangerous teams right now than the Ravens.  I just don't see the Ravens beating two of the Texans, Patriots, or Broncos in back-to-back weeks, which is what they will likely need to do even if they secure the number two seed. 

Signs of Life
For the second week in a row the Jacksonville Jaguars showed some offensive firepower.  Last week they lost in overtime to the Texans and this week they secured a victory over the Titans.  Chad Henne  looks like Dan Marino and Joe Montana combined compared to Blaine Gabbert.  The Jags are getting big plays from suddenly frisky wideouts.  Should be interesting this off-season to see how the Jaguars deal with the Gabbert dilemma.  Did he show enough progress this year to be the guy next year?  Is Henne a viable alternative?  Do they dare draft a new "the guy" as they will likely have a high pick again this year?


No Excuses X2
I don't know what was worse in the Detroit game against Houston on the infamous "was he down" play.  The officials missed an easy call.  I saw the play in a speed watch mode and it was clear to me he was down.  So first we miss an easy call.  Then a silly rule means we can't correct the missed call even though we know it is wrong.  There is simply no excuse in the replay age for getting a big call wrong, a call in this case that likely changed the outcome of the game.  I don't fault Lion Coach Jim Schwartz for this in the least.  Yes, he should have had better command of this stupid rule.  However, the only reason the rule came up at all is that the officials failed to make the clearly correct call.

The NFL has adopted a posture that encourages officials to let them play on when there is doubt in these situations.  Personally I think that impinges the integrity of the game.  The mindset should be "get the call right".  What's next - hide the ball under the shirt plays?


Bigger Wreck?
There seem to be more teams than normal this year that fit the profile of a big ol' train wreck.  These are teams that we thought would be good or that we thought would show big improvement.  In some cases these are teams that we thought would contend for playoff spots.  So who are the biggest train wrecks from among the Bills, Jets, Raiders, Chiefs, Chargers, Lions, Eagles, Cowboys, and Saints?

Lets eliminate the pretenders.  The Raiders, Chargers, and Cowboys fall into the bucket of teams we have learned to not expect much from.  I think we could see the train coming in the case of the Saints and the Jets given the level of dysfunction that followed them into the season.  The Bills?  They spent a lot of money but I don't think there is any great shock that they will be watching the playoffs from home.  The Lions were a playoff team last year and have rarely played like a playoff team this year.  They would be a candidate in any other year.

My big wreck award goes to the Eagles and the Chiefs.  The Chiefs have brought ineptitude to a new high ( or low).  They lose.  They lose badly.  They lose at home badly.  They don't score very much.  They don't have an NFL caliber QB on their roster.  Many picked them to win the AFC West.  Instead they will likely pick first in the draft.

The Eagles 3-1 start included wins over the Ravens and the Giants.  They have not won a game since that 3-1 start.  Andy Reid is as good as gone.  I can't see the Eagles picking up Vick's contract for next year.  Last year a former player labeled this team the Dream Team.  No dream to nightmare catchphrase from me.  I like to think our level of discourse is better than that.  They are a big ol' train wreck though.


Harbaugh looks Smart
I loved the gutsy call Jim Harbaugh made in switching to Colin Kaepernick at QB - though I questioned the wisdom of the move.  Kaepernick played solidly on the road in New Orleans as San Francisco won largely behind the stellar play of its defense.  Kaepernick showed enough flashes that you can see the extra "it" he brings to the table compared to Alex Smith.  Harbaugh now has the chance to refine the offense under Kaepernick for the rest of the season.  If the Niner offense can meet the Niner defense halfway, they become the favorites in the NFC.




You Can Go Home Again
Carson Palmer returned to Cincinnati for the first time since orchestrating his departure with a faux retirement.  Curiously, nobody in Bengal land misses him.  Ok, it isn't so curious.  The Bengals have a capable QB in Andy Dalton and they plundered quite a booty from the desperate Raiders when they traded Palmer last year.  The matchup yesterday wasn't really Dalton vs Palmer.  The matchup was a young Bengal team on the rise vs a funky Raider team that year after year seems to lack identity and direction.  The 3-8 Raiders need to run the table to match last year's disappointing result.
The Raiders have a lot of work to do just to return to mediocrity.



WEEKLY AWARDS

MVP

The San Francisco Forty Niners defense scored two touchdowns on interception returns in the 31-21 win in New Orleans.  The Niner rush also sacked Saint QB Drew Brees five times.  The constant pressure prevented Brees from setting and throwing any deep passes, effectively eliminating the Saints ability to rally from a two-score deficit.

EL BUSTO
Sighhh.  I held my tongue (keyboard) until now, but how can I let pass the latest novel way the Chargers found to snare defeat from the jaws of victory.  There they were leading the Ravens 13-10 late in the game.  The clock was winding down and the Ravens faced a last gasp fourth and 29.  Yes, you read that right - fourth and 29.  Under pressure Ravens QB Joe Flacco dumps a pass off to Ray Rice in the flat near the right sideline.  Rice then proceeds to scamper all the way to the numbers on the left side of the field, turn downfield, and secure the first down (or darn close to it - but if you let a guy get 28.5 yards on fourth and 29 don't expect any breaks on the spot).  The Ravens kick a FG to force overtime and win 16-13.  Charger D - for finding yet another creative loss technique -- this busto is for you.



SURPRISE-SURPRISE-SURPRISE
This week's Jim Neighbor's award goes to the Saints, Packers, and Bears offensive lines.  Yes, I know none of these O lines are among the league's best.  I was nevertheless surprised at their total futility in recent losses.  Last Monday Night the Bears had no answer for the Niners.  Sunday afternoon the Niners did it to the Saints.  Drew Bress might as well have been Heath Shuler for the time he had to look downfield.  Sunday Night the Giants looked like they were doing wind sprints to see who could get to Aaron Rogers first.  The Saints won't make the playoffs.  The Packers and Bears will not get far with those lines.

TREASURE OF THE WEEK
The Falcons edged the Buccaneers 24-23 behind the passing combo of Ryan to Jones and a defense that largely held rookie sensation Doug Martin in check.  The win cemented the Falcons hold on the division and put a dent in the Bucs playoff drive.


TRASH OF THE WEEK
Let's see -- the Steelers lose eight turnovers and still have a chance to win the game (another sketch call on a non turnover late in the game sealed their fate).  One team turns the ball over eight times - -bad.  The other team gets eight turnovers and still can't put the game away - -bad.  Steelers and Browns add to the landfill this week.

NFL Monday Nights - Detmer Leads Eagles to WIn


NFL MONDAY NIGHTS
Koy Detmer Leads Eagles to Win

Nearly ten years ago to the day - -on November 25, 2002, the Philadelphia Eagles played a Monday night game against the San Francisco Forty-Niners.  The 7-3 Eagles were without starting QB Donovan McNabb due to injury.

Koy Detemer started at QB for the Eagles.  Koy was the younger brother of 1990 Heisman Trophy winner Ty Detmer.  The Eagles drafted Detmer late in the 1997 draft.  Detmer played for the Eagles for nine years but only started eight games in his career, five of them in his rookie season.

Detmer played the best game of his career that night in front of a national television audience.  He threw two touchdowns and ran for another as the Eagles blasted the Niners 38-17.  Unfortunately, Detmer fell awkwardly late in the game and dislocated his elbow.  Third string QB A.J.  Feeley finished out the game.  The injury ended Detmer's season.


McNabb would return for the playoffs and lead the Eagles to a victory over the Falcons in the Divisional round.  The Tampa Bay Buccaneers defeated the Eagles 27-10 in the NFC Championship game on a cold, blustery day at Philly's Veterans Stadium.
