lol let's put them both in American Gladiator and see what happens.
I figure Conor takes Atlas Sphere, but Mayweather is surprisingly good with the nerf cannon at assault and Conor's unfamiliarity with American football proves detrimental to his performance at powerball.
It looks pretty spotty for McGregor heading into the eliminator, but Mayweather gets DQ'es for Punching Siren backstage and saying that he's going to have turbo make him a Cannoli and a plate of spaghetti.
