Easiest fight to call is Henderson vs Bisping. Henderson is one of the best wrestlers in the game while Bisping is from the UK where they don't have much of wrestling base. Bisping only has a shot if Henderson keeps it standing but considering Hendo has never been knocked out (and he's fought the best) he'll have to win by decision. Hendo can take the fight to the ground almost anytime he wants (see how Bisping got worked by Hamill a couple of years ago).
