Going for the punt block was the fatal error. Absolutely stupid and needless. You can argue till your blue in the face about whether or not it was roughing, you don't gamble in that situation. You drop back in punt coverage.
We were in the drivers seat at point in the game, the momentum was on our side, and we were poised to deliver the knock out punch. Our defense was dominating the line of scrimmage, we held them deep and we would have gotten the ball at mid-field with a prime opportunity to grind down the clock and score the winning points. Game over.
The penalty completely changed the momentum of the game and shifted the field position battle. We lost the game becuase of those two things.
