There are a few long shot entries. The Bulls could clear cap space with a few roster moves but the knee injuries to Derrick Rose have changed their landscape. The Dallas Mavericks will have cap space and some star power but league executives expect them to target another Heat free agent, Dallas native Bosh.
The Mavericks have missed out in the past three years on LeBron James, Bosh, Carmelo Anthony, Deron Williams, and Dwight Howard. So their track record isn't great. Bos, like Deron Williams, is from the Dallas area, so you imagine that's a pull. Putting Bosh next to Dirk Nowitzki would be weird and awkward but if you really wanted to run a smallball team, it could work, theoretically.
It would also provide a gap between Nowitzki and the future.
It brings up an interesting question of just what happens with Bosh. If LeBron James decides to re-sign with Miami or doesn't opt out, does Bosh look elsewhere for what may be his last major payday? Or stay in Miami to continue the success he's had there, albeit as a third wheel? The drama continues to unfold for the Triad.
