I hope Florian kicks Penn's ass and I don't think I'm going to have a "hindsight is 20/20" moment when I realize, "Of course Penn won." Sorry, but I am bucking the odds and saying Florian takes this. Penn has boxing and jits. Florian has it all. Muai Tai > Boxing because punch + kicks > just punches. And I'm pretty sure Florian has a bigger gas tank and a longer reach.
Yes, I know it's a lame, quick post, more later.
