Haye. Plus he got the tightest Vagina of all Champions in History (every weight-class) Just a Sunday Joke!
HW champs: SNV, Muhammad Ali, Larry Holmes Other: LaMotta, SRR, Basilio, Julio Cesar Chavez, Harry Greb, Duran, Mosley (stood up to Mora's constant 12-round onslaught of power punchers), etc.
I'd actually be more inclined to say Kessler than Froch. Not that he lacks in the chin department either.
vitali that fought lewis, yeah. since then tho, most heavyweights cant get past his jab to land 1 on the button
