I know the play you are talking about, and I remember on the replay it didn't look that bad, although the announcers piled on. I paid attention to Sherman as much as I could last night, and honestly, I thought he played a spectacular, and mostly very clean game. The couple of times he got handsy I thought more "how the hell else are you supposed to play the position".
re: 5 yard holding penalty
I wonder how the ref decides when it's a hold, and when it's PI and 'spot of the foul'.
