This haye and bellew situation is rather interesting i must say!
Only thing i dislike about haye is what fury pointed out... he retired due to never being able to use his shoulder again... then comes back and fights two clowns and claims his shoulder is better than ever and robbing the public by going into ridiculous match ups that are VERY unfair and could potentially be very dangerous too.
NO ONE on this planet can really judge him after his fights since retirement.... they really have been pathetic match ups.
Not saying i think he would, but it would most certainly be entertaining for the sport if bellew did knock out haye... its been 4 years since haye fought anyone decent... after all he's not in his prime anymore and anyone can win on the day... just take a look at the whole fury klitschko situation for evidence.
