I agree with that and should have included a caveat--if he can get his head in control. Capers has also described him as one of the two most improved players from last season (the other being Faggins) so I wouldn't look for Capers to give up on him easily. Peek would be dumb not to respond to a couple of stern lectures from the coaches.
By the way, since we are treating this as some sort of second offense--anyone know who started the Peek/Brown altercation?--everyone seems to be assuming it was Peek. Brown is another young guy that thought he was going to be a starter.
