The Cavs are in limbo. The best kind of limbo, really. Their games don't matter much until the playoffs start next weekend. With three to play, wins hurt the team's draft position and games in general provide opportunities for key players to get hurt.
David Blatt and the Cavs are attempting to limit the latter, and in so doing, might counteract the former:

All three will play tomorrow against the Detroit Pistons in Cleveland, so there aren't really any injury issues outside of Kevin Love's nebulous back situation. This is about making sure the injury issues don't pop up when they simply don't need to. The Cavs aren't really worried about their first round opponent, and they probably shouldn't be. They can use the first round of the playoffs to work out the kinks before things get serious in round two.
You should still watch today's game. Tristan Thompson, Timofey Mozgov, and Iman Shumpert are likely to have big roles on the Cavs for quite awhile. Those guys are suiting up.
