I think it was more to do with Don King but I don't feel Tyson, especially a prime Tyson was scared of anybody. If anything I feel it may of been the opposite. Its easy to forget just how intimidating a prime Mike was. You do not get any more mean & ferocious than that.
Foreman, maybe but Bowe?
Why would a guy who fought Holmes, Lewis, Holyfield x2 (I'm not saying it was a prime Holmes) but why would he be scared of Bowe? One of the biggest waste of talents to ever grace the sport.
I really doubt he was scared of anyone, he may of felt Foreman would be a threat but Bowe, naa I can't see it. I'm not saying he was a bad fighter or anything I just can't see any version of Mike being scared of Bowe, a rather inconsistent guy, often out of shape & unmotivated who threw his title in a trashcan to avoid Lewis.
