To worry about Lin is to admit you don't trust his game. He'll be fine and he doesn't need a fake coach to boost his stats to guarantee that. He is a pg, a pg is suppose to protect and distribute the rock, right?
Wanting more from him is admitting you don't understand the basics of the game. We were never going to win anything playing the way D'ant wanted us to play. D'ant would have never blew out the Blazers and he probably knew if he lost to them it wasn't going to be nice in the Garden. He had no confidence and booked. The smartest thing he did here was to resign.
