It depends on which Tyson you are talking about. If you are talking about Tyson Fury, then I wholeheartedly agree with you. However, if you are talking about Mike Tyson, then I disagree.
Either Byrd fight was more important for Wlad's legacy, especially the total utter domination of the 2nd fight. In fact both Peter fights were better as well. I rate the shutout over Haye as equal to the 2 fights against Thompson, Mercer, Chagaev, Ibragimov, etc. The last 2 were undefeated fighters for unification.
Brewster, Sanders & Purrity are bums? Okay tough guy..........:yep I guess you didn't see what Brewster did to Golota then right?
Ruddock x2, Holmes, Spinks & Thomas are 5 better wins than anything on Wlad's resume. Add to that the likes of Tubbs, Tucker, Bruno x2, Bonecrusher & others, is fairly obvious Mike has the superior resume.
I'd put big money on Vlad doing this as soon as big bro klitschko is retired. Who iss going to stop him? Only thing that stops this is the commissions. H2H Current Vlad could win Tyson has the better resume though.
