If we're talking belt holders as well: Wlad Lewis Smith AJ Wilder (highest in terms of his hardest punch, but lower overall) If only lineal: Wlad Lewis Tyson Foreman Liston or Louis
#1 Foreman he koed the best competition cleanly. #2 Liston cleaned out the division before he got the title shot, so may not fit the topic. #3 Tyson a deadly combo of speed and power. #4Louis see the Tyson comment, but Joe Louis had better accuracy and punch placement . # 5 Lewis had dangerous power in his right hand. #6 Marciano wasn't a devastating bomber more a attrition bomber #7 J.Frazier see Marciano can be flipped between the two. #8 W.Klitschko hugh man, excellent power. #9 M.Baer excellent power, without steroids or supplements. # 10 A surprise one Tommy Morrison. He couldn't do much else, but his left hook may have been more dangerous than Frazier with one shot.
Walcott faced a shopworn Louis whose right hand was going and a prime Marciano when he himself was coming off the rails.
