An excellent boxer vs puncher match up IMO.
Wilder can end a fight with one punch, but one trick ponies can suffer in re-matches.
Fury is a problem because he's big and can take one of those punches, mobile, good brain(for a boxer) and just better boxing fundamentals.
Not sure if all that is enough though. Wilder could hit him once and end it...or Fury could frustrate him and gas him out.
So much more interesting than a Mayweather fight... in any case. I'd take Fury because a rematch favors the smarter fighter.
