You knew it had to happen. With Devin Harris playing off the charts and Marcus Williams' role in question and in doubt, something had to give. Last night, Williams sat out the first half, leaving backup duties to Darrell Armstrong. It wasn't an accident. Lawrence Frank was upset about Williams' shot selection vs. Chicago and let him and everyone else know. He has to be more consistent, said the coach. I need more time, said the player. And apparently, he's not the only Williams with focus issues.
