I like Shavers and Tua in particular for this, but all of them could cause a stir against Joshua, whom I think has become a greatly overrated commodity. Yes, Joshua is big, strong and can punch. He can also change his style to adapt to seriously overweight and static opposition, over whom he holds massive physical advantages to win a near-shutout victory. But, like a lot of these bigguns, they can oft get their comeuppance against opponents, who come to fight. Joshua is no exception here.
If Morrison came out, like he did against most of his opponents, then we could have a short, exciting clash. And I wouldn't bet certain on either man. Tua, good grief! I know he can get overrated on here but if he wants a war and AJ does!!
AJ can't afford to get involved in wars, as witnessed by millions against Ruiz Jr. The likes of the fighters mentioned in the OP would probably force one on him. Tua withstands anything Joshua has in his armory, in my opinion; making him particularly problematic.
AJ beats all of them. He'll jab and box Tua's head off, KO's the rest. I'd give Ruddock and Morrison the best chance, but the stars would have to line up for them to win.
If AJ had those five opponents coming up next, he wouldn't go undefeated in them imo. He might be favored over most of them and be better than most of them individually, but those fights are dangerous. A lot of big punchers. He would have a loss or two.
last year or so I would have favoured AJ, I thought this kid looks the real deal, he is too Big & Strong, the HEIGHT and the REACH is too much for the Traditional HW's, a different Division completely, S-HW. but he has shown to be too inexperienced, stamina problems and also a bit uncertain in how to regain himself, again inexperience. can he come right??? we shall see, IF So, we have a real talent in the division. IF So! and for the record, I don't think we'll see Fury meet AJ. John Fury is already telling Tyson to retire, take that anyway you like.
