I'm still trying to figure out how they say the 'call stands' on the replay. They placed the ball on the 42 and he was clearly past the 42. He was either at the 41 or just in front of it. I would have thought they would have placed the ball near or at the 41 and measured.
There some discussion in the chat yesterday on why Percy Butler went after the ball on a punt when it had been touched by the Panthers. Here's Jeremy Reaves explaining it.
Watching that replay again, I don't know why he didn't just try to run to the sideline and past the corner instead of cutting back in to where more defenders would be.
