I can go back and forth on this one. I don't think it's wise to go comparison shopping and say "this guy beat so and so and that means he'll win". Wlad has been very dominant the last 10 years but the one thing we have never seen is him troubled by a good inside fighter, let alone a joe frazier. Joe Frazier had a knack for wearing down fighters in his career and would give Wlad trouble inside. Joe stops wlad late.
I've said it before and I'll say it again. Wilder's competition is nothing to write home about, but he's blown them out of the ring like a top fighter would.
One thing I'll say about Wilder and his lack of competition is that he showed those bums don't belong in the ring with him. He takes care of business with them like how a top fighter would. You think Malik Scott goes more than one round against Wlad? I don't and he didn't with Wilder.
