7. Most Career Knockouts (131)
Set By: Archie Moore
Bestowed one of the sport's great nicknames, "The Old Mongoose" fought for longer than pretty much anyone could conceive. Over four different decades he stepped into the ring for an astounding 219 professional bouts, winning 185 of them. The 131 knockouts is particularly staggering because, in this day and age, who is going to fight 131 times? Most guys don't fight more than two or three times in a year. Moore fought 15 times in 1937 alone! You'd think he was probably severely brain damaged, but he actually lived to the ripe old age of 81.
