It's pointless to argue if he would have done it. He didn't and the fault lies solely in his own doing. Some fighters are wired for one moment of greatness, but don't have the dedication or consistency to maintain it beyond that initial burst of glory. Bowe was a great example. Fury is another. The very thing which drives them to excel is not sustainable over the long run. Had the steroid stuff not derailed Tyson something else would have, or he'd have half-assed it in training one time and got beaten by someone miles below him in skills or talent. I don't think there's too much to feel sorry about here in terms of squandered talent, and I'm saying this as a genuine Fury fan. I just accept that the man was never going to be a long-standing champion, and I think I always suspected as such.
I'm not sure. I'm not even sure he would've beat Wlad in the rematch. As dull as their first fight was, I really wanted to see the rematch. I think there's a good chance we would've seen a different and better Klitschko in the rematch. He would've known he had to approach the rematch differently. Threw caution to the wind and took more risks perhaps. Wlad also had a great mindset, he would've been more determined than ever before and probably underestimated Fury in the first fight. Fury thought he had cemented his legacy with that win over Klitschko. But one great win doesn't achieve that IMO. We'll never know how good a champion he could've been. He was the champ for one night only.
