Well, they already do come out with an entourage including trainers and lackeys, they wear colorful outfits, they cut promos, they call each other out, they have theme music. Then there are scandals about the refs calling a match too early or something, about guys who cheat by hitting guys in the groin, etc. It isn't far removed from pro wrestling as it stands. But as things move more toward entertainment and less toward "sport," they move further and further away from the "pure" nature of the "sport," as it was originally intended by some. The rules are always changing to make things more "exciting" and entertaining in all sports (i.e. changing the rules in baseball, basketball, and football to make them more score-friendly, hockey lets its players fight, etc.).
