JJ Watt, Houston Texans

J.J. Watt looks like he was scientifically created in some laboratory, deep in the heart of Wisconsin, with the intention of destroying opposing quarterbacks. How else can you explain a human being that stands 6’6, weighs 290lbs, squats 700lbs, can clear a 61″ box jump, and consumes 9,000 calories per day. Teams had to devote at least two — if not three –of their offensive linemen to block him on every play. Before his injury-shortened 2016 season, Watt was almost unquestionably the best defensive football player in the world.
