strikeforce had a draw with diaz and as so they handed him strikers to make him look good. diaz hasn't and doesn't face top ten fighters ever, GSP dismantles them on a regular basis. it's really an easy fight to call.
I'd like to see this fight. Both those Diaz boys have a mouth on them that I'd like to see GSP shut. He's on a whole different level and at the peak of his career, much like Hughes was before GSP took the thrown.
