Holyfield's at 10, he's there. However, it's hard to believe that Gatti is on this list while some fighters with far better chins than Gatti's (like James Toney) aren't.
Thanks for shitting up the front page with the half dozen threads you've created in the past half hour.
Joe Grim might have had the best chin ever. An unskilled middleweight and and shopworn from nearly 100 losses, it still took Sam McVea 13 rounds to KO him.
Holyfield made it, but not Billy Graham, Kid Gavilan, Carlos Monzon, Juan LaPorte, or Wayne McCullough.
