CLEVELAND — Rasheed Wallace  has said all season that the playoffs are what motivates him, but after a disastrous regular season, the playoffs have been pretty much the same story for the Celtics  prized free agent acquisition.
Wallace picked up three quick fouls in the first half and went 1-for-5 in 13 minutes of Game 1 against the Cavaliers . He was also a liability again on the defensive end where his rotations were slow and his help defense was lacking.
“He has to play better, bottom line,” Doc Rivers  said Sunday. “He has to play better defense. The offense will come but he has to be a better defender. We can’t wait. He has to play better.”
Rivers elected not to use Shelden Williams  despite the heavy foul trouble that Wallace and Glen Davis  found themselves in early in the game. That might change, although Rivers didn’t quite his tip his hand on that front.
“He is in the discussion every day,” Rivers said of Williams.
Is he is it more today?
“No,” Rivers answered. “But he definitely is in that discussion.”
