This is a tough call but a really good problem to have, when and if we are fully healthy.

Garland
Mitchell
Wade
Mobley
Allen
First off the bench
Rubio
LeVert
Osman or Stevens
Love
Lopez
Unfortunately, one of Osman or Stevens will be getting cut out if we truly see this team fully healthy. It's likely a matchup dependent bench group as sometimes Love can be the 5 if we go small, which would let room for both Osman and Stevens to play at the same time. But, it's also a pretty rare situation when all 5 bench players are playing at once.
Neto, Okoro, Windler, Diakite, and IMobley are your deep 5, which honestly isn't that bad of a mop up crew either.
Deepest Cavs team we've had in a long time.
