Destroying an unproven commodity always carries with it the risk that it backfires on you. One of those weird paradoxes of boxing where a dominant victory actually gets you less credit than struggling to a win or losing in a gallant fashion.
I doubt he will get very much credit as most will say Joshua was unproven and too inexperienced The real credit will come when he thrashers fury in a potential rematch and fully redeems himself
