Fury may have a shaky chin.. but unlike the rest of those guys he's actually beaten world class HW's. I think that if he keeps improving, his chin won't be as much of a factor(similar to Wlad) Fury can box pretty well when he wants to, he easily outboxed KJ who is a very good boxer who other than that has only really lost to Vitali. against Cunningham he was showboating and brawling not boxing.. Peter Fury was very upset with performance, and I don't think he will let Tyson make the same mistake against Haye.
if you watch those two fights closely, you'll see that KJ threw almost the same amount of punches in both fights, something like 5 punches a round
Well thats how KJ fights.. and it works.. just not against world class guys like Vitali and Fury. Not an amazing win for Fury, but it proved that he can box. if he comes in with the same approach against Haye I think he'll win.
