No disagreement...whether under center and blasting it up the middle into the teeth of the D with 9 defenders coming hard or in a shotgun and doing something similar, it plays into the strength of the D. Now, if its a game in which the O line has been dominating the D line, that's a different story. But it seems with the Colts, IU, etc, there seems to be guts to go for it on 4th down, but very little creativity when it comes down to the play itself
