I'd give AJ a slight edge if he comes in lighter than he did vs Takam.
When you have two men who hit hard, and have the potential to finish opponents, it largely comes down to who lands clean first. I think AJ's more technically sound than Wilder, too, for what it's worth. The Wilder we saw vs Stiverne isn't a danger to AJ. That's because he was telegraphing his shots and was completely open. He won't do that vs AJ - because of fear. That said, Wilder is a danger. He is quick and powerful - and much lighter on his feet.
