no wilders coordination and balance are not that good orthodox he will leave himself off balance everytime if he tries to shoot straight lefts
He can fight southpaw, doubt he could box as a southpaw as barely looks like a boxer in his orthodox stance.
No Fury might fight as a southpaw to make his stance help keep him further away from the right hand and Fury has fought southpaw in previous fights, Wilder never has.
If Wilder fought Southpaw it would nulify his own powerful right hand, which is his best shot along with the left hook.
Fury should fight righty, but I have seen Fury fight very well as a southpaw. Perfect fight against Chisora!
he can fight at orthodox but not box if he tried to fight southpaw he'd put himself at a disadvantage
