This was supposed to be the battle of the draft steals: Rajon Rondo, taken at #21 by the Celts vs. Marcus Williams, taken at #22 by the Nets. Instead, Williams will be at home in New Jersey nursing a sprained wrist, the severity of which remains unclear. Rondo, who has been a revelation for Boston, will play. Still, the Celtics with their young roster will be a challenge for the Nets who remain winless. Lawrence Frank plans on playing the starters more beginning Wednesday. He may have to.
