Joe Frazier, Joe Louis - prob my fav 2 of all time....Holmes, even Foreman. And the 80's/90's era guys - Lewis, Tyson, Holyfield, Hearns, Hagler, Leonard - all very dominate and respectable boxers.
Hard to leave out Marciano, and then the rags to riches underdog types like Braddock and Wepner. Boxing, much like "rasslin" - was always about the personalities and then backing it up in a tough fashion. I miss that.
