My predictions for this era:
Kobe will go down as the Jordan of this era, Rose as the Magic, Howard as The Dream. Durant, if he doesn't put on weight, will be the player who was almost one of the greatest but never quite there. If he puts on muscle and drives more, he'll go down as the greatest scorer.
It's tougher to say with Lebron. He'll either go down as the Dominique Wilkins or the closest thing to MJ. Who knows?
Btw those comparisons aren't meant to say they'll be as good, but who they'll could be comparable to. There's no way Kobe is near MJ or Howard is near Hakeem.
