This was the first Cavs loss against a good team. They were seemingly playing up for the big games and not showing up for the crappy games.
They matchup with the Bucks well because the Bucks are a poor shooting 3pt team that can't fully exploit the slow defense of the Cleveland backcourt. Their only good win aside from that was the Washington Game where Lebron played like god.
wins - Milwaukee x2, Boston, Washington, Chicago
Losses - Orlando, Brooklyn, New Orleans, New York, Indiana, Atlanta, Houston
Only Chicago and Houston are misplaced.
