I;m def. not criticizing Mike McCarthy on this one because of what PFWT said - we needed trickeration on a 4th attempt to punch it in from a yard out, plus like you said wpr, it's very easy for us to critique when we're not wearing the headset. By the book, I have no problem with what Mike did.
However, the "I will suffer no consequences for my decision' arm chair qb in me says we should have. The team was seemingly playing with house $ at that point in the game since they had been outplayed to that point, I had no confidence that we could drive/stop a drive in OT, so as long as you're there, might as well take a shot.
