He needs to fight some brawlers so he can find openings for his power. Well, assuming that he actually has real power. Considering his opponents, it could all be an optical illusion. I would pick Price over Fury, Wilder, and Helenius. Price has the best chance at winning a title at this point.
Deontay Wilder needs to step up. Fight Tony Thompson or something, it'd be a decent opponent given what he's done so far.
Wilder, Mitchell, Scott, Perez, all need to step up.
