JJ Watt is a freak. There's no other way to describe it. How do the Houston Texans lose Mario Williams to free agency and Brian Cushing to injury and still have one of the better defenses in the NFL? JJ Watt. Why? Because at 6-foot-5 and 288 pounds he does things people his size should not be able to do. Things like jump five feet in the air from a standing position. Good luck, quarterbacks.
