Pure aerobic endurance aside, gridiron players are some of the most athletic people on the planet when ranked on things like quickness, strength, vertical leap, agility, and so forth. There is an event called the NFL Scouting Combine where college athletes are tested and ranked on these factors: http://en.wikipedia.org/wiki/NFL_Scouting_Combine http://en.wikipedia.org/wiki/NFL_Scouting_Combine Perhaps the most interesting differentiator between american football and other sports is how much of it is about raw athleticism. It's a power, speed and size arms race. Most other sports are more about how good the players are with specific skills.
