I have seen that same question posed many times. Always good for an online argument
. I train MMA at a BJJ gym. Lots of the techniques we use are derivatives of wrestling. I can tell you that guys who come to BJJ or MMA from a wrestling background are pretty far ahead of guys who come out of a TMA.
One skill that I know I want to improve is takedowns. I was training with a blue belt on Monday night and he said man if we have to start standing I just don't really know what to do.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
