Who is your BOAT?

SRR had more losses than Patterson, Frazier, and Holyfield, in fact he was 1 loss away from having twice as many losses as Holyfield, most people remember SRR's somewhat spectacular avenging of the LaMotta loss, however SRR lost both fights with Harrington and Pender, lost to Fullmer twice drew once and won one

I actually rescind my SRR vote because he's the casual pick, there I said it

From an athletic standpoint Hagler is better than SRR and might have even beat him in a fight, athletically probably no one tops peak Evan Fields aside from some guys having a better 15 round game but never having close to equivalent strength

 

Were any of those fighters ever 129-1-2 at any point, though?
