They already have Matt Barnes?
Barnes shooting and defense are as inconsistent as celticsbloggers think Jeff Green is.
Only thing he does reliably is mean mug for the camera and rebound.
Right, so why would they need Gerald Wallace?
Steve Balmer has too much money?
Wallace is an upgrade on Barnes in every aspect except shooting, which is their biggest need at the position so yeah its a no go. They lack any backups at all behind him though.
Really they need Barnes + another rotation player.
