Even if you are perfect, there is nothing to stop people from baring false witness on you. Oftentimes, a mere allegation is enough to make you dirty. This could be a case of a jealous woman who had her feelings hurt when Peyton didn't give her enough attention.
Did he moon players when she was present? Maybe. Stuff like that happens all the time; if you choose to work in a locker room, full of over-dosed testosterone football players expect unrefined horse play to occur. Locker rooms are full of nude bodies to begin with;
so I am pretty sure the players think nothing of baring their butts.
Did he kind of sit on her head when she was examining his foot? Maybe. Did she encourage such behavior by acting like "one of the boys" leading up to it?
Peyton was what, 18 at the time? He was already being treated like a hero. It would be easy to cross the line in that circumstance.
And do I excuse such behavior? Not in the least. Do I believe Peyton was not guilty of a "crime" during this? I do. He's been the classiest player in the entire NFL in his tenure. I don't think you can fake two decades of spotless behavior.
This appears to be about getting ratings and attention. But, boy, when you are on top of the mountain, better be careful, because that is who they love tearing down.
