Scott Smith (mediocre on the ground)
Did you watch that fight? I don't remember it going to the ground at all. It was a stand up one way beating. Smith is known as a power hitter with a strong heart and good chin, and Diaz absolutely destroyed him on the feet. I mean he was playing with him the way Anderson Silva plays with supposed strikers.
Not to say he's the next best thing, but he's certainly one of strikeforce's best fighters. If he was in the UFC I would put him ahead of a lot of the top ten WW's. But he's poor man's version of (the old) BJ Penn, lots of potiential, not enough work ethic.
