I've been long on the Jeff Green for Anderson Varejao straight up train and I think that is more likely now. Pairing Noel with Thompson and Zeller pretty much sets the Cavs down low and Green is a big upgrade of Alonzo Gee. Seems to make a lot of sense for Cleveland, especially with Varejao's injury history.
For Boston it makes sense if they are going all in for one more run. Varejao, if healthy, is more valuable to Boston than Green, and Varejao is expiring after the year (or has a team option for 14/15). Thus, he comes off the books sooner than Green, which would make more sense in a rebuilding situation.
