Above .500 is a bit much, but I feel like they should hit 35 wins at least, so long as they can get plenty of minutes out of Afflalo, Melo, and Lopez, and their rookies give them some solid production.
Melo's underrated imo. I think people would be surprised to see how consistently "above-average" Melo-lead teams have been throughout his career. It's not like a Paul Pierce situation where the guy makes 4 playoffs in 10 years (never cracking 50 wins) before climbing on KG's back. Melo's teams are generally pretty good when he's healthy.

Dude made the playoffs the first 10 years of his career on two different teams. The surrounding line-up isn't spectacular, but PG - Calderon, SG - Afflalo, SF - Melo, PF - O'Quinn (underrated imo) and C - Lopez looks like enough to make the playoffs in the dreadful Eastern conference. Let's not forget that the 7th seed this year had a losing record and arguably not a single legitimate starter.
