Ward has the opportunity to show, what I believe, is the chasm between him and Kovalev. No disrespect at all, Kovalev is to be taken very serious and could absolutely win the fight.
I just don't believe it'll happen. Ward has too many tools, his sharpest possibly being his inside ability. Kovalev is used to guys running from him, or keeping distance. I think Andre will do what he always does, no matter who it is, and that's to methodically get inside, make it ugly & break him down.
