Assuming they don't come back and win the championship, what can they do to overtake GS? After Warriors lost, they added Durant, I'm thinking Cleveland will have to make a similar move. Obviously someone not on Durant's level, but better than Korver.
I'm thinking they need to upgrade the SG position. JR Smith is a nice player, but you can definitely upgrade at that position. Either that or find a true center who can protect the rim, but the list is limited.
Also, find a competent backup PG, Deron Williams is garbage. What happened to his game?
