They seem like a pretty easy 50 win team. I mean before Lebron got hurt they were only slightly off that pace last year, and I think they are clearly better this year. Health will always be an issue, but I think they have enough depth to get by.
PG - Rondo, Cook, Caruso
SG - Green, KCP, Daniels
SF - James, Dudley
PF - Davis, Kuzma
C - Cousins, McGee
Another veteran minimum or two type players and I think that team has plenty enough to win 50 games.
