...there's any question that Leach was probably thinking that the kid was milking it and he was trying to deal with him because of that. But anyone who has played football has been subjected to similar things. Probably not at this level, but coaches talk smack when you're hurt, they challenge you, they run your *** off, etc.
Leach doesn't deserve to lose his job over this incident, but I suspect there's probably a bunch of other things behind the scenes that are contributing to the decision. But it's pretty apparent to me that the kid is a *****, too. This reaks of, "Do you know who my dad is? I'm going to tell him and he's going to get you for this." Shut up, stand in the damn corner until your head quits hurting, and go play football.
