As a smaller guy, the main selling point of all this submission nonsense is the "allows smaller guys to level the playing field against bigger guys" thing. So what's in it for the bigger guys, bearing in mind they could probably smash 99% of the population based on size alone? I don't imagine you could really relate to the odds facing Royce in the early(er) days, so who/what inspired you? (If you say Frank Mir, well, just don't). And does any big guy really train BJJ from a self defence perspective?
