I don't think there are 10 or more guys like LeBron and KD, I don't think there are more than 1 more guys like them, really. LeBron, KD, Melo, that's it. Guys who can turn a game on its head if they're on their game, because their mix of skill, size, strength (in Lebron and Melo's case), and athleticism are just about unguardable. It's the same problem the outgoing generation had with McGrady, Kobe, and Pierce.
After the top tier, there's a bunch of 'but' guys. Yeah, Paul George is super talented, BUT... And so on.
