Watch 'Feijao' grunt as he prepares for Henderson at StrikeforceMaggie HendricksMarch 3, 2011Rafael "Feijao" Cavalcante hits hard. If you didn't know that already, this video will convince you.Feijao won the Strikeforce light heavyweight belt by virtue of those hard hits, TKOing "King Mo" Lawal in August. In fact, those hard hits have earned him nine wins. Of the 10 times he has had his hand raised, nine have come from TKO or KO. (The other one is a submission.) He's never had a fight go to a decision.On Saturday, those strikes will be tested by Dan Henderson, who has some big strikes of his own. Henderson beat Vitor Belfort and Wanderlei Silva in Pride before scoring highlight reel knockouts of Renato Sobral and Michael Bisping. Tell us: whose power will win out?Follow Cagewriter at Strikeforce in Columbus on Facebook and Twitter, and follow the good folks at Blackhouse MMA to win Feijao's handwraps.Thanks to Bloody Elbow for the heads up.
