There's no compelling reason for him to have "next" for Fury. Wallin's claim to fame is that - excluding those rounds where Wilder knocked down Fury - he probably managed to win one more round against Fury in one fight than Wilder and Whyte collectively did across four fights. He's a very skillful boxer - but what he isn't is exciting. He can give most opponents a boxing lesson - but he's not a big puncher. He couldn't miss against Breazeale but never looked like stopping him despite landing a few hundred shots on him. Breazeale has a bit better chin than some, but he'd seen better days by the time Otto got a hold of him.
