McGee has fallen out of Brian Shaw's rotation and the Nuggets should look to move him. The Celtics need a big and McGee could work out.
But what could work for this trade to work:
Celtics receives: JaVale McGee
Denver receives: Gerald Wallace, Vitor Faverani, Was. 2nd rd. pick, Phil. 1st rd. pick (Which will be a 2nd rd pick in 2015 if 76ers are 1-14)
If the C's don't want to use their 2nd rd picks, the C's can use some of the trade exception that they have built up.
What do the Celtics get: A big in JaVale McGee who runs the court, can play in the P&R with Rondo, solid defender and rim protector.
What does Denver get: A veteran present in Gerald Wallace, who can be a vocal leader but also Vitor Faverani who's contract can be terminated at the end of the season.
If the Celtics stay pat and don't trade for a rim protecting big before the trade deadline, they need to be looking at Kentucky's Willie Caluey-Stein in June's draft.
