Journeyman Bigfoot Martin was landing big shots at will on Bowe before a bs cut stoppage. If bums were finding homes for their power shots on Bowe then a fast, powerful HW with quick reflexes like Joshua surely could do the same. Bowe was out of boxing at 29 because he was a human punching bag.
Bowe KO within 3. Joshua would have to kill Bowe. Joshua is in incredible shape and has one shot knockout power however I don't believe he is seasoned enough, yet anyway, to handle a fighter of Bowe's caliber. Bowe would be too relentless and aggressive. I see Joshua getting outboxed and roughed up. He will rock Bowe, then its lights out. HW division making a comeback!
Bowe looked great feasting on smaller fighters I think he could have his hands full with a big, technically sound super heavy like Joshua. I could see Joshua finding Bowe with regularity and if Biggs could rock Bowe twice it wouldn't shock me if Joshua blew him away. But Bowe is far more proven, has far quicker hands and put his punches together better than AJ. You can't really favour AJ in this match up, he has far too much to prove to even be considered a challenge to Bowe.
If little domestic level Whyte with a bum shoulder could rock AJ, Bowe blows him away 100%. Biggs was a lot better than Whyte.
It's weird, I was just thinking about this as a match up myself. What it comes down to though is what Bowe shows up.
