Well, it doesn't bear thinking about. Would he be the worst HW champ ever? He's only got the title shot becasue he and Haye are British. Dog****.
This fight should happen, being an Olympic gold medalist, Prize fighter champion and European champion are reason enough for me. In fact Harrison is a better challenger than Haye is a champion. Haye's an ABC champ, Wlad and Vit are the really deal. For that reason, it's a good heavyweight fight between an Olympic champion and a Cruiserweight champion. A good british fight between popular and well known fighters. Big money.
He would be unbearable. People think Haye is bad but Harrison, who is deluded at the best of times, would literally melt.
