Those guys you listed are all considerably worse than his next opponent, and AJ could easily bring them to him if there were any point in it. Gerald Washington and Charles Martin are both football players who fight like it, they suck and Joshua would kill them. Andy Ruiz, Joe Hanks, have you seen these guys man? He doesn't need to go anywhere at this stage, may as well keep building the fan base at home and fight whoever he can for some experience, Wach is certainly a good opponent.
