I think that article hits the nail on the head with Iverson. He's an incredibly gifted scorer, and when he's hitting it's fun to watch. It just isn't winning basketball. If he could play within an offensive system, limit his shots to the open ones, and create for others the rest of the time, he'd be playing winning basketball...but then he wouldn't be playing the style he's always played.
This is why I'd rather have Baron Davis. I haven't looked at the stats, but I'd bet Baron doesn't take as many shots as AI. A Warriors fan on another board was just praising Baron's passiveness on offense.
The closest the Sixers and AI came to a Championship was when the discrepancy between East and West was at its most extreme, with the West pretty much guaranteed to spank the East in the Finals. The East was so awful AI was able to get all the way to the Finals with his one-man show, with players like Aaron McKie and Eric Snow playing the best ball of their careers. He squeaked out an OT victory over the Lakers in the Finals, but the next four games weren't even close.
