KG at 30 was still twice as good as Love is at 25.
Also, KG is a once in a generation/lifetime type player. Him and Pierce are in the same class as Jordan, Bird etc.
Did you ever see Bird or Jordan play? In their primes?
Yeah, I try to stay away from the deification of players, but if anyone deserves it, it's Bird , Jordan, Magic, and, I'm really, really sorry to say it, Lebron (and, Russell, but I'm trying to stay current era).
KG in his prime for a year or two might have approached those guys but he doesn't compare when you look at the body of work.
He is probably a tier or two below, on par with Duncan, Kobe, maybe Shaq, although I don't think any of those guys dominated at their absolute best the way Shaq did.
