You're kidding, right? Moving to PPV in the 1980s destroyed the general popularity of boxing and essentially made it go away in people's minds, although Mike Tyson (Fury's namesake) was hard to ignore for a few years. It's the same phenomenon of radio guys like Howard Stern who made much more money by going to private networks but lost the general attention. You can't hide the main event behind a $100 paywall or whatever it costs and make it a general preoccupation. The Ukrainian Klitschko brothers got almost zero publicity, despite being massive guys and great fighters. Tyson Fury arguably gets more attention than any since, because of the oddities of his story. It's a bit mysterious how he is so good when he looks like all those palookas that would be easily dispatched by top fighters in the 1980s. Judging by how quick Usyk was on his feet and with his head (but with a big weight disadvantage, and height, against Tyson), I think Fury needs to lose 20-30 pounds before that fight happens, if it does. But he is a powerful fighter and at 6'9" and 250, I think he would be a monster in the ring (he weighed in this time at 276).
