Dude is 27 fighting guys that are geriatric, aren't boxers and are much smaller than him. He gets credit for being a competent boxer, but that's it. If he wants to be taken seriously as a boxer he can work his way up the rankings in actual fights, not glorified exhibition matches.
It's a tricky position to be in because he's a big name
So, his team and promotion want to find that balance between fights that actually challenge him, while simultaneously being able to sell tickets and ppvs.
He has 4 years of competitive, if he were to fight pure boxers at that level, he'd be fighting amateurs or early pros.
Almost all of those guys don't have a name, so you can't really build an event with them.
That's why he's fought Nate, Anderson, Tyson.
He's offered millions to Ali's grandson, was scheduled to fight hasim rahman Jr, fought Tommy fury, based on this, I dont think his team is actively looking for easy fights.
But, a lot of it just comes down to business and trying to find that balance in opponents and business.
There really isn't a lot of options when you take all of this in mind. At least not until he gets good enough to challenge ranked names with profile.
Fury rematch should probably be next though.
