To me, it mostly boils down to two things (barring injuries--any major injuries and it's all out the window):
1. Cavaliers' offensive rebounds
2. Warriors' turnovers
I think that, while James is the most talented player in the league, the Warriors are clearly the most talented team in the league. It's their series to lose. Consequently, if they can control their own defensive boards and limit their turnovers to a manageable number, there really isn't much Cleveland can do. The Warriors just have more two-way stars and role-players than the Cavaliers do.
If the Warriors give up a bunch of second chance points or are careless with the ball, Cleveland can really push them. If both happen, then Cleveland has a great chance to win the series.
Consequently, I don't think the Warriors will play a ton of small ball. I think they'll use it as an occasional change of pace, but I think they're going to want Pachulia and McGee snagging defensive boards most of the game. I think Cleveland will go small more often than Golden State, with Tristan Thompson at center.
