The reality...

There are a lot of reasons why you didn't see these guys in the UFC, not the least of which is that they live in China, not Los Angeles....

That being said, most would be serverly burdened by SIZE.. old UFC's had no weight classes.

Some would have beaten other TMA'ers.... all would have been utterly confused by something like BJJ. Royce would have tapped them like he did everyone else. It was an approach and techniques that they had never prepared for
