So I watched every snap of Carpenter and it is actually concerning to me how wrong most people in this thread are. He had one absolutely terrible block and that was when he went to block out on the DE Greg Hardy and he made a great move and went right by him on the first play he was in the game in the second half. It was ugly and I suspect that is why people are having such a problem with the game he had. Other than that he played great and made every block. The only other two others I can see anyone having a problem with were when he went to block Kuechly twice in the first half. One he inexplicably just didn't block him but Kuechly wasn't involved in the tackle anyway. The other one he was supposed to block Keuchly in the middle of the field on a play that was going toward the sideline and Kuechly made a great play by tackling Baldwin. It was the one where Baldwin was tackled high by Kuechly.
Other than those 3 plays including two of which were really minor, he played a great game. I suspect people saw the Hardy play where he admittedly looked terrible and applied it to the rest of his game. I would take that performance from a lineman all day.
