The best bait the Celtics have is still Green if he keeps playing the way he is.
The Cavs have young players at PG, SG, PF and C. They need a SF.
Green, Bass and Melo for Sideshow, Walton and CJ Miles work numbers wise.
Really depends on how much they would value Green and Melo. (Melo could easily be replaced by Sully)
