palhares and rustam chsiev

who would win in a grappling match?

I would suggest that promoters of that match up have a pair of good orthopedic surgeons on stand by, as it would likely end in mutually destroyed knees.

Aoki, I just saw Rustam vs Vinny Magalahes,. That is a good question you asked. They would make a great Metamoris match.
