You have posted some odd stuff, so this is not the most off the wall stuff you have posted, but its close.
Beyond the fact that was you describe is an assault (also a pretty odd way for a 21 year old to ask out a 23-25 year old), there is the tiny matter of not having the balls (sack?) to Man up and admit what he did. Instead, he let the trainer concoct a "mooning" excuse and ask her to blame another football player (a black one). When that did not fly (and when a witness failed to back him up), he made up allegations to tarnish her reputation relying on animus toward the black football players to help explain why he didn't like her.
And as yeti points out, there had been a previous reported incident that his family's lawyer had sealed. So Peyton might read defenses like a book, but he seems slow on the uptake otherwise.
