I think Diego is a bad matchup for GSP. Diego will obviously look to Ground n pound GSp and I think he will be successful in doing so. Diego is the bigger man in terms of muscle mass and I think he could get GSP down and mount him. However, if GSP keeps it standing or can get on top before Diego takes him down, then GSP wins via KO or submission. Don't like the match up for GSP though. I think Hughes would have a better chance at beating Diego. Yes, I realize this sounds dumb cuz GSP just killed Matt, but Matt is a better offensive wrestler than GSP and would match up better with Diego!
