From an interview with Fan 590 AM in Toronto by way of MMA Digest:
"In some ways he is a mirror image of fighting Matt Hughes and he's just a smaller...I think he's just a smaller and not as strong version. But he actually in my opinion might put out a higher output because he's a cardio machine and all those different things. I think that St. Pierre pretty showed the way, excactly what to do to Sean Sherk, and kind of just put him away because that night you could just tell Sean Sherk has no answer for that style. You stop a couple of his shots and he doesn't know what to do from there out."
I wonder if Josh Koschek is reading this because I think GSP will do the same to him.
