Colleen Schneider vs Liz Carmouche

Both these aggressive ladies rank among the toughest competitors in MMA. Which is probably why they stretched each other to the limit when they squared off in Phoenix, Arizona in 2010--at least until before Carmouche finally capitalized on her opponent's mistakes. You can catch Schneider in action at SFL 2 on April 7 as she takes on Cherie Buck of the United Kingdom.
