Moreno will be the faster guy and much better on the ground here. Serrano is one of the lowest guys in the division. Benoit is just a big brawling guy with a lot of power. His takedown defense is shaky and his ground game isn't much at all. He's so big for the weight class that I think he doesn't do well in fast paced fights. Someone on Bookie Beatdown mentioned this and it makes sense.
