Re: MMA training
It's a helluva lot more skillsets you have to cover. I give pro MMA fighters all the respect in the world (well most of 'em) as the range of skills they are required to have is huge. As Ray Mercer demonstrated so ineptly against Kimbo, there's no use great stand-up skills if you are unable to defend against being taken down or have no clue what to do once you get there. Likewise you can't get away with being just a great grappler/juijitsu person either. You need skills in all 3 areas of fighting.
