I'd imagine JDS would work his TDs hugely if he fought Overeem cos in a pure K1 fight Overeem would kill all the top UFC HWs the only guy who could possibly hang with him is Pat Barry and i wouldn't fancy his chance either.
Edit: Also i'm pretty sure Overeem has muscles that dont actually exist! No way that guy aint roiding!
No, he would not. He might destroy Brock but JDS, Cain and Carwin would murder Overeem standing. I still don't get why anyone thinks Overeem is some awesome K-1 striker when his only claim to fame is a fluke KO over Hari. Hari kicked his ass in their rematch.
Then comparing Ben Edwards to JDS? You've got to me kidding me...
