Exactly Bretimus! It also goes to show how there's a lot of skill involved - Especially concerning the ground game. It's like a physical chess match. You also don't need to be the strongest guy or the biggest guy to pull out a submission win. Factor in someone like Roy Nelson, yes he is big and strong but to take one look at him you'd figure he's some out of shape redneck. He's one of the best heavyweights in the sport right now, in large part to his well rounded ground game. Sure, he can pack a punch but if a bigger, more "athletically built" guy got him on the ground there's a very good chance Nelson could pull out a submission via a well placed arm bar or rear naked choke.
