Sheed could have added toughness, size, experience, and HEALTH. Sheed might have been banged up by the time the Finals rolled around... but he at least was out there playing.
2011: JO + Shaq = 72 GP (including Playoffs)
2010: Rasheed = 103 GP (including Playoffs)
IF you don't think he would have helped then your just hating on Sheed.
in 2010 Rasheed Wallace gave The Celtics a steal and a block a game with 22 MPG... nobody gave them that this past season.
Per 36-
Sheed '10: 14pts, 6reb, 1.6ast, 1.6stl, 1.4blk, 1to, 4pf
Baby '11: 14pts, 6reb, 1.5ast, 1stl, .5blk, 1to, 3pf
Numerically they may be comparable, but you can't make up for the fact that EVERYONE in the league can finish over Glen Davis.
