I watch 100+ match of Bulls in last 2 year because I'm Rose fan, qualified enough to make that judgement.
There is reason why Bulls defense seems a lot more solid with Asik/Gibson than with Noah, Noah only excel in help defense (switching)but due to his baby arm he can't be rim protector n block shot, that's like half of purpose from bigman help defense, his post/man defense also not better than Ibaka. Bulls defense will a lot more scary with Ibaka than with Noah.
Let not act Noah isn't liabilities on offense either, he can pass then? I rather Noah shoot his tornado shit than Ibaka's keep improving J.
Btw OKC maybe can get Taj Gibson cheaper next year than sign this extension, same player. Or even better fit.
