One thing do boggles my mind on that last few minutes about that foul that had given 3 shots for Walker. Is that considered a shot attempt?

Base on the referee's decision, it is a 3 point attempt and I think it really is a 3 point attempt knowing that they are trailing at that time. Its a mistake that Butler tried to swat it but who cares now we have the winner already and it will not be reversed anymore.
A coach who was in the playoffs when he is still in the Thunder. Maybe he can help improve this Bulls team but not going to the playoffs.
