I think Joshua has better boxing skills than Wilder but he is static at times and now appears to be more cautious then before which would actually work against him in this, we all know he won't outbox Fury he's a level below in terms of skill and boxing IQ. He is a pretty compact fighter tho and has very good finishing instincts so i wouldn't write him off, There's every chance Joshua would loose to Wilder tho, he wouldn't be able to box the way Fury did last night and in the end Fury did still get dropped twice no doubt Wilder would catch AJ and more frequently then he did Tyson. Joshua was the real looser from last night, especially after Hearn and himself disparaged the fight beforehand, AJ apparently couldn't see anyway Tyson would win and was talking about fighting Wilder even if Fury won.
Tbh after last night those comments sound like they come from a man who's more then a bit worried about fighting Fury, I think most fans now view Fury as the rightful number 1 regardless of how many paper belts AJ holds Fury is the liniel champ and the man who beat the man whatever Hearn or AJ say until Joshua fights and beats Fury he will never be viewed as the real champion in many eyes. Fury schooling AJ would be a disaster for Sky and Matchroom, bit hard to be sold as some machine if you'v just been toyed with.
