It isn't always but i'd still argue it's more competitive overall than UFC's heavyweight division. Povetkin was elite at one point. Chisora is a tough gatekeeper, journeyman type. He's not the best boxer in the world but he's a tough guy. You really think Tai Tuivasa is good? Is he better than Arreola? You think an old, shot to bits Arlovski, Rothwell or Walt Harris are great competition? I think UFC has like three or four top heavyweights and the rest aren't particularly great. Ngannou, Miocic, Lewis, and Gane. Blaydes, Rozenstruik and Volkov. 7 guys but 4 are really in the mix to win a belt.
