But it works Eddie.
In Boxing they are all about cashcows and protected records. We never got Joshua vs Wilder or Fury.
In MMA we usually get all the fights we want and some more... except some cases like Jones vs Aspinall.
Who cares? That's two examples, and Joshua is one of the most overrated fighters in boxing history. No one cares about Joshua or Wilder anymore.
We got Pacquiao Vs Floyd (eventually), Golovkin Vs Canelo, Tank Vs Garcia (not exactly an amazing fight, but a good fight between two "stars"), Beterbiev Vs Bivol (amazing fight between two undefeated pound for pounders). Years ago we got Canelo Vs Floyd, both undefeated. We got Crawford Vs Spence semi recently, both undefeated at the time. We got Canelo Vs Bivol, very good fight and risky fight for Canelo, turned out he got completely dominated by Dmitrii.
We got the Beterbiev Vs Bivol rematch, even better than the first fight. Usyk Vs everyone, spanking Joshua twice, then schooling Fury twice. We got Usyk Vs Dynamite Daniel, and now the more compelling rematch given that Dubois seems to be at his peak.
Not an example of the best fighting the best, but just the other day Benn Jr moved up 2 divisons and put his undefeated record on the line against Eubank Jr for an epic Son Vs Son battle.
We also have Inoue and Nakatani agreeing to fight, two of the best fighters in the world, both undefeated.
And there's plenty of examples of big/intriguing MMA fights not happening. Obviously Jones Vs 'Gannou never happened, Jones Vs Tom looks like it isn't happening, we didn't get GSP Vs Silva, or Silva Vs Jones.
