But has anyone ever seen George Mikan play?

I've seen him on video and based on what I saw he doesn't belong on the list. Not nearly as athletic at many if not most of the current centers. Plus the competition was nothing like it is today. But maybe a "real old timer" can set us straight. He was, however, the NBA's first really dominant player. That does go for something.

It was a different game then. Mikan is the reason (according to Wikipedia) that goaltending was made illegal, the foul lane was widened, and the shot clock was introduced. I believe that any man who is creative enough to force rule changes deserves special consideration for creativity and resourcefulness. That's one of the reasons Deacon Jones was so great in football.
