He's still capable of playing his way pretty effectively, but he can't play any other way. Nor does he try to play any other way. And that shit doesn't cut it in the NBA.
The same reason why I couldn't fuck with Iverson. You gotta adapt.
And he wants to pick his moments to try on defense now. That doesn't cut it either.
Now trust, I know he's probably being the "escape goat" for this Bulls team right now. He's an easy target. And I know he's trying his best to adapt. But without the ball in his hands, he's just a guy.
You can't be the smartest guy in the room forever unless if you don't have the athletic abilities that made set you a part from other guards.
