I think with the double big lineup and the size and strength of harden and dmitch I think Jrue at the 3 could actually work although the cavs lose a decent amount of depth but I assume one of meleek Thomas , cpj or proctor can play rotation mins next year and kretj and potter are decent rotation guys

Harden , D-mitch , Jrue , Mobley , Allen Thomas ,Vit , Tyson , Tomlin , Potter CPJ , Proctor ,Batum, Bryant
