I think Chicago should be the favorites, Cleveland has a lot of talent but their "young" talent has no experience in the post season, so it would be a learning curb for them
While Chicago has their core/philosophies set already, the talents they added just fit in together very well, adding depth and defined roles, along with the experienced, skills developed, chemistry gained, and versatility in talents added while Rose was sidelined
They were a TOP DEFENSIVE team without Rose and were a TOP team every year despite being doutbted every year, they needed some scoring to go with their post season, they achieved that
In addition to the versatility in their BIGs and G/F's complimenting their cutting/3pt shooting/passing/ and multiple ways they can beat you with their spacing as a TEAM and 1v1
Bobcats are quite under the radar as well but I don't see how teams can match up with their speed/quickness/athleticism and shooting/spacing with Jefferson healthy, with the addition of Lance Stephenson
Their BIG's can all shoot, outside of Biyombo, so with Lance/Kemba being able to force double teams easily, they will be very tough
Maybe Wizards match up with the Bobcats the best
and
Orlando is my comlete possible sleeper, dependent on Elfrid Payton and development of Olindipo, health of Harris/Vucevic, 3pt shooting and spacing provided by Frye/Ben Gordon, and rotation of their athletic young bench on both ends being effective consistently with Harkless/Nicholson/Kyle O Quin/Aaron Gordon
What I don't understand is the trade for Fournier and losing a scoring threat like Affalo who was also very good as a defender and shooter/scorer as well
