The Cavs have lots of starters and bench players that can function perfectly fine against the type of ball pressure the Warriors are capable of bringing. They already know how to deal with Steph, and they can absorb Klay's points, but KD is a real challenge for them.
For the Cavs to win, KLove cant stink it up till the last game, he has to contribute 20+ points a game when hes out there.
DWill and Kyle Korver completely neutralise whatever scoring advantages GS had off the bench last year. DWill is a bum, but for 15 minutes a game, he can bring that heat. His handles, shooting and passing ability are crucial answers to Shaun livingston.
