Consider Brian Burke of AdvancedNFLStats.com. As Burke wrote for the New York Times:
With 2:08 left and the Colts with only one timeout, a successful 4th-and-2 conversion wins the game for all practical purposes.
A conversion on 4th-and-2 would be successful 60 percent of the time. Historically, in a situation with 2:00 left and needing a TD to either win or tie, teams get the TD 53 percent of the time from that field position. The total win probability for the 4th-down conversion attempt would therefore be:
(0.60 * 1) + (0.40 * (1-0.53)) =
0.79 WP (WP stands for win probability)
A punt from the 28 typically nets 38 yards, starting the Colts at their 34. Teams historically get the TD 30 percent of the time in that situation. So the punt gives the Pats about a
0.70 WP.
You dont need to know much math to know 79 percent is a greater likely win percentage than 70 percent.
Personally, Im not completely convinced of probability conversions when it comes to a game with as many variables as football. The Colts defense is not the average defense. This isnt playing against St. Louis in the second quarter. Crowd noise matters. And so on.
Then again,
Peyton Manning(notes) isnt the average quarterback either at his own 30 or the Patriots 30. Of course, neither is a pass from
Tom Brady(notes) to Kevin Faulk, two clutch, veteran players.
Still, it
ought to count for something that all of the probability formulas go in Belichicks favor. The majority of people issuing blistering attacks can cite the assumed probability that punting was the best option. That cant be deemed more accurate than actual probability even if you dont believe fully in the math.
There are few things worse in sports than when conventional wisdom of how something should be done (because thats how its always been done) sends a chilling effect for innovation and ingenuity.
There are few black-and-white decisions in the course of a football game. One may be better than the other, but its never 100 percent to zero percent. Belichick didnt make a good choice or a bad choice, he made his own choice.
Having a coach think for himself based on great insight (statistical or otherwise) should never be called a bad move.
