Besides the fact that a buckeye shoved him in the back, conveniently ignored by the refs, and he held up his hands as if to say I'm not hitting him on purpose. It did appear he lowered his head at the end but I'd have to see it again to reference the entire sequence to better understand that in relation to the entire sequence.
The push in the back was a key as I saw it which I had not see originally. Much like Brown's late hit on the Illi. QB last week only to discover he had been shoved into the QB. Something looks egregiously bad only to be shown as a set of events contributing to a seemingly nefarious ending. Don't want to make our young men into a comparison of the undisciplined PItt defenders penalty machine.
I the end, like many other calls, plays, penalties we see it differently. LIfe goes on. Losing Shelton sue did hurt us as the game wore on.
