So Lebron, Delly and JR Smith pushed GS for 4 games last year before running out of gas in Games 5 and 6.
As I said before, Love and Frye are the X Factors. If Love gets it going early, good things happen for the Cavs. Frye has hot throughout the entire playoffs so if him and Delly (along with Jefferson) can be consistent off the bench this could be Cleveland's year. If Curry (who is banged up) and Thompson get it going, you won't stop them but can only hope to slow them down
Kyrie and Steph I think will neutralize each other. Klay will probably be guarded by JR/Shumpert combo and maybe even Lebron. Iggy won't have a tired Lebron to "keep in check" this time around. And Draymond won't get away with dirty play with Lebron on the court so Thompson/Mozgov combo will be able to contain him. Love's subpar defense can be overlooked if he continues to be consistent from 3
