Man, thats pretty fucking weak. Why would you be scared of getting taken down, because if the wrestler doesn't know BJJ he could end up taking you down and putting himself right into an armbar/triangle/kimura, especially from a purple belt.
I'm taking BJJ right now and I want to learn some wrestling. I'm going to be transferring to Texas tech in 6 months to a year, if I got into really good shape would I be able to walk on to the wrestling team? I know I will get thrown around and get my ass kicked, and I don't plan on competiting since i have not wrestling experience, but If i got my ass kicked by some college wrestlers I would eventually get good at takedowns, and good takedown defense for MMA, right?
