Ray Mercer: Not offering a high enough bribe (to Jesse Ferguson) to have his opponent throw fight. Most notable Jake LaMotta opponents: Being welterweights fighting a guy often ~10 pounds heavier.
Lupe Pintor, Vicente Saldivar, Mike Weaver and Chango Carmona were all slow starters. Joe Louis, a bit of a sucker for the counter right hand. Kostya Tszyu, a bit of a sucker for the overhand right. Yoko Gushiken, couldn't get out of the way of a lead right. Johnny Bratton, a bit of a weak chin (broken 3 times)
When Edwin Rosario was hurt, he froze up in the manner of a Frank Bruno. He just stood taking shots without clinching.
Lewis actually got up at 6 when dropped by McCall. While he was wobbly and the stoppage was fair it would have been just as fair to let him fight on. The count was also happened to be a touch quicker than other famous KD's. I'm not saying the shonk was in but when King has a horse in the battle nothing surprises.
As great as he was Arguello was very upright and really needed to be planted to punch. Sure took some taking advantage of tho.
Holmes, rarely threw a left hook. Ali, didn't punch to the body. Ali,when he jabbed his right glove went out of the guard position. Liston, his massive jab often pushed opponents back out of range. Liston, never learned to cut off the ring. Patterson,[if you think he was great,] sometimes caught square on which contributed to his numerous kd's. Lewis sometimes pushed his jab. Lewis , complacency cost him twice. Foreman ,in his first career didn't pace himself and ,if he didn't get his man out of there early sometimes shot his wad, ie Ali and Young. Marciano,poor balance, sometimes missed a punch and fell over. Marciano ,cut prone,two fights may have been stopped in more modern times with less lenient referees. Marciano, would have been dsq'd in the UK for the Cockell fight. Loughran,lack of power. Joe Brown brilliant as champ ,sloppy in non title fights. Jimmy Carter,[if you think he was great,] "inconsistent"=handcuffs in some fights,usually recovered his," true form," in rematches.
