The UFC shat the bed with HW. It just stopped caring outside of Randy and Bork. All the middling talent hit the bricks while the rest just kept aging. Putting up even a little effort to promote Stipe-Ngannou is the most the UFC has done lately. It's also hard to find skilled big guys just because there are fewer big guys. But yah, it's fucked. Nobody with two brain cells to rub together is enticed by fucking Reebok money. The UFC's own model is what keeps it fringe and chills real talent. HW is just the most obvious example. But if you poke into any division you'll see the same shit.
