Lebron Honestly isn't that far off of Bird. Really a few more seasons of normal Lebron James play and a championship and it is a wrap. You can make a serious case against him my all time favorite Kobe and many of the other greats.
I'm not even a James fan I always root against him, but it is hard to hate his game.
As to the question KD has the potential, but lets see how healthy he can stay over the next 10 years.
One of the most overused sayings on this forum
"and its not even close" When in reality it is quite close.
