Bulls in 6 or 7. More balanced team, more cohesion and chemistry built over years than a new team obviously. I also think we've seen time and time again that to win titles your defense has to be at an elite level and the Cavs don't have the personnel for that as it stands IMO. If they add Marion and a couple other defensive specialists for minimum, obviously it may change.
Depends on Derrick Rose. If he's 100%, I'd lean Bulls at the start of the year. But the Cavs have more offensive weapons. And elite ones, at that. The Bulls are great defensively, but the Cavs have a ton of offense. If Cleveland learns to play any kind of decent defense, I think they're the better team.
The Bulls have 2 high upside "wildcards" that could tilt it in their favor. Nobody has seen McDermott or Mirotic play an NBA game yet but both have intriguing upside that fit well with the Bulls culture. Both are lottery picks (Mirotic projected in top 5 of this years draft according to Fran Frascilla because of his success overseas at such a young age.) Those are 2 pieces that I think could put the Bulls over the top because they can overwhelm you with effort and depth. Thibs won't have to play anyone 40 mins a night which means by the Playoffs they'll be in much better shape like the Spurs have been.
