The similarities between the two are pretty obvious. So much so, that when James hit a 3 in one of the exhibition games, the announcer mistakenly did the Buudddyyyyy Hield thing.
However, I think James has some talents that set him apart from Buddy (not better, just different). In particular, I think James is bigger, stronger, and better around the rim/in traffic than Buddy was at the same point in his career. We'll see where it goes, but I'd love to see James continue to develop this unique part of his game.
