LeBron moving to the Cavs has actually spread out the balance of power in the East. Miami still has a good team, and it reminds me a little bit of the 1994 Bulls team after MJ's first retirement. Obviously, Wade's health is a big issue, but I feel like he's going to be VERY motivated this year after being tossed aside by LBJ.
Then you've got the Bulls, replacing Boozer with Pau is huge, then bringing in shooters like McBuckets and Mirotic is going to be awesome for their offense. If Rose is back that's another strong team.
Indiana should still be strong despite likely losing Stephenson, who I think will be signed by the Hornets, who also have a very strong team with a great, young bigman rotation around Al Jeff and excellent perimeter defenders.
Washington brings back their same team essentially but replace Ariza with Pierce. They should be a little better than last year with Beal and Wall improving.
Atlanta was playing amazing with Horford, so if he's healthy I expect them to be very formidable.
Then there's us, bringing back the same team expecting improvement from JV, Ross and DD. Also added some depth with Lou Will, James Johnson and the Brazilians giving us arguably the deepest team in the league.
All look very formidable heading into next season. The only playoff team I see regressing are the Brooklyn Bank-Breakers after losing their best perimeter defender in Livingston and Paul Pierce.
