From section214's comment in the recap thread:
I'm incredibly glad Reggie Theus has seen fit to replace Kenny Thomas' minutes with some Justin Williams. That said, we could use some more 3-Wil. He may not fix the rebounding problems himself, but he can't hurt.
Also, a fiction writer could not come up with anything better than Justin having a huge twin brother named Jason. Combined with Dan-Dan Artest, Sacramento's All-Brother team would destroy fools in some tackle football.
