I'm in the Belichick camp on this one and fascinated with the controversy (seems maybe Brian is too). I'm a Simmons fan, but I think his column on this is pretty weak - (http://sports.espn.go.com/espn/page2/story?page=simmonsnflpicks/091120 )
Among the many flaws in his argument: using stats on the number of times a team has had 3 fourth quarter TD drives to win games is misleading. You'd have to look at the number of times teams scored two fourth quarter tds to come within 6-4 points (because 3 points or less and the team will be driving for a FG, not a td), and then see how many of them will succeed on their final drive. Also, I think him bringing up the poorly-called series leading up to fourth down is inapposite: no one is arguing about whether blowing those timeouts was bad. It obviously was. And the play calling is a different argument. The argument here is do you go for it or punt, and the statistics show that it is smart to go for it. Does emotion override the statistics? I say no. Besides, it is a professional athlete's job to execute in the face of emotion and pressure.
