Go to youtube see if they have that fight still up. Frank takes a few to his face, that is like Frank Shamrock blocking method. I personally would never have let Cung kick my face. Just a personal choice though.
You bring up a very good point. We really have not seen Frank's ground game in quite some time, and I agree that Renzo dominated him on the ground. Overall I enjoyed the fight. You could tell at the end of the fight, Frank was really hurting. When I heard how much damage was done, I am amazed he stuck with it for as long as he did!
Saw this over at bullshido today: http://www.bullshido.net/forums/showthread.php?p=1950555#post1950555 Short version, EliteXC probably have words with their fighters to keep it standing whn theyb are fighting one of the "names" in their promotions. I'm not gloating, honestly. The gif is priceless: http://www.bullshido.net/images/slice-petruzelli.gif
Seth Petruzelli clarifying his statement: http://www.sherdog.com/news/news/petruzelli-fights-controversial-statement-14697 Short version, EXC offered him a knockout bonus, pre-fight, and he didn't think his radio interview statement would be taken the way it was. Besides, it's not like he's known for his killer Jiujitsu game. He's a standup fighter with a little wrestling. I like watching him 'cause he throws some fancy kicks. Watch the second season of TUF, dude even tries a jump spin kick at least once.
