Sure he is valuable but is he dependable? Has he been consistant on and off the court? Is he a distration? Does he have maturity on and off the court?
No.
Is he getting better? Yeah. Is it contract motivated? Maybe.
Does his inconsistancy give him leverage in negotiation? No.
Its one thing if he sprains his ankle. Its another if you try to elbow some one in the head.
Im going to speculate the league warned him after he nearly took Sephaloshia's head off weeks ago. Thats why the suspension.
Im not into anti knick discrimination. Basically I think kNicks in playoffs and going deep is great for the league. Why sabotage it?
