Has JDS even been put on his back in any of his fights?
I'm going to go with Cain on this, but if JDS wins, I wouldn't be surprised either.
I think JDS's strengths are obviously his stand-up game and being agile for a large guy, and then also his takedown defense.
I think Cain has drastically improved his stand-up from that Kongo fight...though that will be tested with JDS for sure. While JDS has great takedown defense, Cain has never had a problem getting anybody tothe ground, even larger guys much bigger than him.
I can't comment on JDS's ground game because i've never seen him on his back. I do remember him being on top against Brandon Vera though.
Actually, I don't think i've seen either guy on their back in the guard....???
I'm going with Cain on this fight.
