The Lakers are in a great position to play musical chairs with players. They are coming off a title, and good players want to play for them. The La La location is also a factor.
On the other coast, the NY Nets are also in the same position. They haven't won a title, but they have accumulated enough stars to be a ring threat to the Lakers. That makes them an attractive place for buyouts, as they have shown.
So it's really down to the Lakers and the Nets. They've used existing NBA rules to accumulate the top two teams. LA vs NY.
If I were Silver, I would be concerned about this. It's just too easy for the biggest markets to get star players. I don't have a solution to this. It's his problem.
The Celtics, by the way, had a similar advantage in '08 when they won a title. They threatened to establish their old dominance. But they were unlucky with injuries, and Wyc et al weren't willing to spend to keep them on top. So Ainge had to choose the slow, hard way through the draft. It hasn't really worked as well as expected.
