I'd love to see that Ortiz rematch
Then you're in luck because theres like a 90% chance thats his next fight.
I dont see the point tbh. Its not like it was a super contentious fight the first time, and Wilder hasnt exactly run out of fresh, highly ranked opponents to face yet either, even outside of AJ or a Fury rematch.
Wilder may have huge one punch knockout power, but he's still one of the worst, long term heavyweight champions of all time. One trick pony with laughable technical ability who has ducked anyone that could pose a real threat to his awful reign.
His CV after 42 fights is full of absolute shit, and for all his "incredible" power, he's had some hilariously long fights with some of the utter crap he's faced. The only half decent win he's had in so many fights is Ortiz, and he nearly lost that.
A half fit, ring rusted, overweight Fury absolutely schooled him (and Wilder only took that fight thinking Fury was going to be vulnerable, considering those things) and Joshua will walk through him comfortably. Dillian Whyte would batter him too, which is why he and the WBC have so desperately avoided him.
You're right about his resume, its weak for 40+ fights. Hes also very technically limited but tbf - hes 6'7, has quite possibly the biggest one shot KO power in history, and when he throws it down the pipe (as opposed to the windmill) it is lightning quick and extremely accurate. That 1-2 on Breazele was like a flash.
A lot of guys have better skillsets than him and SHOULD beat him, but its always going to be a scary situation because of that power and how it can undo everything in one second. Fury did win (unofficially) but even he had a major scare eventually, and hes a 6'9 giant who is also the most defensively sound guy in the division. AJ should win but its probably going to be a dangerous fight. He cannot box tentatively because letting Wilder stay in there for a long time means hes going to land that shot eventually, but he also cant afford to get overly aggressive and walk into a shot. He'll be needing to find the right moments to get inside and take Wilder out, theres not much margin for error. Joshua isnt exactly a twitchy mobile kinda fighter either - not much footwork, head movement or feints and those are the things that should buy you time against Wilders right hand, because he'll either not throw it or he'll start windmilling at the air in frustration, leaving him open.
I am not convinced Whyte beats him tbh. Hes decently skilled, tough, gritty and has okay power so he'd have a shot, but all I can picture is him getting stung by that right hand and doing the chicken dance. Parker could be more interesting as (contentious decision loss aside) I think hes got a better chin and is quicker than Whyte. Povetkin would probably give Wilder more problems than most with his inside game and head movement too.
