I think it would be easier to do top 10 for every 20 year period.

I will say that I've always felt Jordan was overated. Yes one of top 5 ever, great great player. But far too many people believed the nike commercials.
tough list to do, might alter it later on
1.wilt
2.oscar robertson
3.jordan
4.bill russell
5.larry bird - magic johnson tie

, forver linked
6.akeem
7.bob cousy
from here imo its really tight
8.john stockton
9.kareem abdul jabbar

10.julius erving, counting aba career
I forgot jerry west who imo would be somewhere from cousy to erving
maybe this means i could drop kareem
