He has ONE stoppage in his Prime while fighting guys who could severely crack...... He was stopped when washed up on his feet more from exhaustion despite Holyfield threw the kitchen sink at him... His other losses happened when he was shot beyond shot. It is clear that you have never been in the Ring, not even sparring. fact. A shot to shid Tyson impersonator took mulitple flush right hands from Lennox Lewis, MULITPLE, until the TKO, and he was never out of it, he just said F it in the end...........Rahman took O N E of those flush right hands from Lewis and he was counting sheep for the 30 count. Fact. As far as McCall or Tua are concerned, when they got hurt they backed off and rather lost then go out on their shield and fought to survive.......Tyson never backed off and always fought to win......both Holyfield and Douglas said that Tyson is at his most dangerous when he is hurt.......Steward was shidding briggs in Lewis's corner because he was dead afraid Tyson would clock Lennox while hurt........ Tyson's chin is a solid 9..........IMO there is no 10.
