If they start now, they can dunk Charr in a tank of water and rehydrate that old stick of beef jerky in time for the fight.
Charr is awful. AJ should KO him early unless he falls back to timid AJ and then he KO's in the middle rounds.
Does Joshua really need another build up fight like this? He doesn't have many fights left, surely he could just go for something bigger? I mean I'd still watch it and Joshua should win decisively but its not a good match up.
