I believe you are right David. People can go on and on about the superiority of a particular art, but if it has not been proven in competition then it is pure speculation. The UFC has some of the best fighters in the world and I would say about 90% of them have a major wrestling background. A little of everything needs to be learned to deal with Submissions, striking and grappling. To people that might have a different view on the UFC, I can assure you that it has changed drastically since its first couple of years. These are highly trained athletes at the top of their game.
