At the start of the series, there was some doubt as to who would see more playing time backing up in the post, Glen Davis or Rasheed Wallace. It's ended up being no contest.
While Davis won Game Two almost by himself with a monster game (23 points, 8 rebounds) in place of the suspended Kevin Garnett, Wallace has never had a chance to make his mark. He's played plenty of minutes in the series but hasn't seen the ball much or done much damage off the glass.
Over the first four games, Wallace was averaging just seven points and 1.8 rebounds. Doc Rivers noted earlier in the series that Davis would see more playing time because ``he moves his feet on defense better." That's clearly been a focus, especially with the Heat having so many players who like to drive the ball to the rim.
