Whoever wins it's a great fight. After rampage beat Chuck a few years back his only losses are to Wanderlai (twice) and to Shogun and has wins over Ninja, Arona and Matt Lindland (among others). But, Chuck's on a 7 fight win streak since that loss and continues to look like a more and more well rounded fighter. I'd have to give the edge to Chuck, but with 2 heavy hitters like these 2, who knows?
