Can't W.Chandler also SG and PF (depending on matchups obviously)?
Also, if Barbosa can't be dealt for a TPE (like the one the lakers have), then deal him to a team that can take on salary like Indiana. I was just checking Indiana's roster and they only have 13 players at the moment, and they are just below 44 million in salary this year. So, they could conceivably take on Barbosa for a conditional 2nd rounder or something. It would be a rental but a backup backcourt of G.Hill and Barbosa isn't too shabby. + they have Lance Stephenson and AJ Price too.
