The Bulls got a surprising push from the Bucks, having gone 6 games. Both teams play physical, so I'm sure there will be plenty of drama.
Prediction: if the Cavs can withstand not having Smith for 2 games and come out of Cleveland with a split, the Cavs can win. I'm predicting 2 wins in Cleveland for the Cavs in games 1-2. A split in Chicago and a win back in Cleveland for game 5. Folks, the Cavs have that killer instinct. Cavs win 4 games to 1.
Worst case scenario says Cavs in 6..
This series won't go 7.
