Stephen A is a clown. Unless the Lakers have a great season and make the playoffs I don't see him going there. It'll be the same as the Aldridge situation. He'll wanna go to the team that gives him the best shot at winning not the biggest market.
If KD leaves Oklahoma City my bet would be him taking his talents to South Beach. Miami looks like a team that could potentially be Cleveland's biggest threat in the East. They got the steal of the draft in Winslow. Whiteside had a breakout season. Re-signed Dragic. Wade had a bit of a resurgence last season. If Bosh can get back healthy the Heat could be dangerous.
The issue with the Lakers is while they have some solid young talent with the likes or Russell, Randle, Clarkson, etc. they're so young and likely at least 2-3 years from developing. Durant nor any star player is gonna wanna wait around for these kids to mature.
