Don't even go there, at some point your going to have to draw a line on the list of the best players ever and say generational and non. You can't do that, you own't even be able to come up with the same list.
Mario, Gretz and Orr. There has been some good analysis that those three guys put up seasons that were just better than any one else by a significant margin. I call those three the big 3, you just can't argue any one else had a better season. That being said, career wise is a different topic.
Any way, don't even bother trying to make a list. Also AO doesn't belong on the list even if you could.
ps ps. Who the hell is Bill Durnan?
