Why Can't The Big Show Just Wrestle?

So one of the big non-wrestling matches at this year's WrestleMania XXIV is The Big Show versus Floyd "Money" Mayweather in a mixed martial arts match. Since the beginning of the spectacle known as WrestleMania, they have used celebrities from the worlds of sports and entertainment to attract the non-wrestling audience.

At WrestleMania 21, The Big Show went belly to belly in a Sumo match that lasted less than a minute. It has been reported that Show left the WWE to pursue a boxing/MMA career. If that's the case, good for him. But he came back to the WWE, that's World WRESTLING Entertainment and he will be in a match at WRESTLEMania. Let's see him wrestle.
