My son is like that, so I'm getting a better understanding of players like him.
He plays college football now. His coaches admit he's the best corner on the team. He went to one of the top high football schools in the nation and learned how to play the position. The other guys on the team don't know as much as he does because they come from lesser programs. His DB coach has even told me this. They love his toughness on the field, his brashness and his playmaking ability. But they don't start him because he is (was last year) a redshirt freshman, and they want to play older players.
But it frustrates my son that he has to wait his turn when he knows he's better than the other guys. That saps his energy and crushes his spirit. It makes him have little regard and respect for his coaches. Even though I tell him to remain patience, sometimes players, when they know they're good and when they're told by their coaches they're good, but are treated like they're not, they get discouraged.
Real players want to play. And when they don't or can't, they lose respect for their coaches.
Maybe this is the case with Hill. We'll see.
