The nerds say 4 yards to go is a bit far to go for it with that "short" a FG. The data says you should be between the 40-45 to go for it in that situation...the break even point where it makes sense to go for it at the 35 yd line is 4th and 2. A FG wouldn't have ended the game though, and there was something to McCarthy knowing that his D was bound to cough up the winning TD regardless.I dunno man, you just have to wonder if Dallas would have been better off kicking the FG.
