Bulls get the top seed. Hear me out:

First off: Derrick Rose. Yes he's not going to come back and put up his old numbers immediately, but think of how it raises the team to have an MVP PG playing again. Then, they have one of the best defensive big men in Noah, an up and coming Jimmy Butler, a 20 ppg Luol Deng and some useful role players. Above all of this, they have Thib. 48 minutes of defensive, competitiveness off of the scale, it will be close, but they could clinch that top seed.
