Well, it's seen before that players just get so frustrated over their contract situations that they don't wish to be at a place anymore. I don't think so, and i most certainly do not hope so, but him being frustrated over this, could interfere with his play on the field. Would not be the first time. I really don't get why they don't sit down with him and tell him: "Hey look, we want you to be on this team for a long time, and we will give you a new contract as soon as possible, but with the current CBA, its not possible to give you a deal that'll work out great for both parts!" What they should have done is, they should have given him some kind of raise this year, as they have done with Johnson.
