Honestly, I think Varejao's trade vaule around the league has to have taken a pretty big hit. The guy just cannot stay healthy. I love the player, but if you can't play, what good are you?
Varejao easily still has more value than Bass (staright up), but at this point, there is now way I'd trade Jeff Green straight up.
Cleveland should have traded him when he was healthy. Pretty much tied to him now, unless their willing to take pennies on the dollar. Even if he manages to make it all the way to the trade deadline next season healthy, teams are still going to be wary of his history.
