I was impressed with Mir's ability to survive those hellacious punches and still keep a cool head and get the tap.Kind of reminded of the early ufc days with Royce and kimo.The huge size difference just shows that techique is superior to strenth.I remember when I first started rolling I got caught in a armbar by 175 lb guy that looked like a total wimp, I was a lean 215 .Strength is a great asset when you learn when to depend on it and when not to depend on it .But with Lesnar continually working his sub defense and his striking, I think he will definatly be a solid competitor in the future.
