It would have been a close fight which Fury is capable of winning if he uses all his physical tools to his advantage. But he doesn't do that and has been already knocked down by fighters with little punching power. David Haye would have came in with his usual defensive crap that he does against tall fighters, avoiding most of Tyson's punches before finding his way through his weak defence. I don't really think it would have been a great fight and I think he had a shoulder surgery because he wants the Vitali fight before he becomes a politician.
