It should be close, but the Cavs HAVE to win that matchup if they want to win that series, mainly on the glass. The Cavs have not been turning the ball over much, and they have been crushing things on the glass which is how they're winning right now, they have to limit the amount of possessions the Warriors get and make every missed shot by them costly. The Cavs are playing at the slowest pace in the playoffs, and while the Warriors can play slow basketball they can't afford to do it and give up offensive boards. If the Cavs win the rebounding battle they could win the series, simply because they're basically playing possession basketball with a pretty good offense.
Also, If I'm the Cavs, I tell Mozgov not to step up when Bogut gets the ball in the middle and basically force him into shooting. I don't get why teams rotate over to him like he's an offensive threat, if he gets the ball at the foul line and starts to make a move to the rim all he's doing is waiting for the defender to collapse so he can kick it to the corner for a 3.
