I think yes. A lot of Tyson fans think that he is the greatest fighter of all time, a sort of flawless unbeatable king of the ring but its just not true. I'll explain why: 1) He was ko'd five times, suggesting his chin wasnt top notch.
2) He couldnt fight on the inside. (this comment will cause some argument, but check out a video on Youtube "Mike Tyson was not an inside fighter" it shows that most of his damage was done mid-range and on the inside he did little more than clinch.)
3) He could be out-boxed and frustrated by clever fighters with good movement, check out the first round of the Tyrell Biggs fight and the first min of round four vs Larry Holmes. Both men boxed on their toes and totally neutralized Tyson.
Tyson was a good fighter but not as increadable as people make out.
