#3 To compete against more actual combat sports athletes
There was a lot of talk around who would win in a legitimate fight- a professional wrestler or a combat sports athlete, especially before the business had been exposed. A possible match between Muhammad Ali and Hulk Hogan, for example, would be something that people would discuss for hours on end.
Kids still have the same kind of fascination for all their favorite combat sports athletes and therefore the whole idea of a boxer taking on a professional wrestler, for example, holds great appeal to them. Becky Lynch would be slaughtered by Ronda Rousey in a real fight, but in the fantasy world of professional wrestling where both women are at par, there's the possibility of an upset when the two clash in the ring.
So, in keeping with FOX's legitimate sports approach, the idea of Braun Strowman taking on MMA fighters (who follow sports entertainment and want to transition into the business) like Daniel Cormier or Stipe Miocic could happen at some point in the future. Even Velasquez will want new competitors to fight against and Braun Strowman could be an ideal opponent.
Braun Strowman's legitimate 'strongman' roots could give him the background needed for such incredible multi-sport dream confrontations.
