Am I, a relatively passive observer when it comes to most sports (just don't care enough to make a lot of wagers, crunch stats, etc.), accurate in assuming that the staggering growth of athletes is going to become an increasingly big issue, particularly in high contact sports like football? What I mean is, these players are getting bigger, stronger, faster, hitting harder, etc., but their ankles and joints aren't really getting any more durable. Is this accurate? If so this is really bad news for the NFL.

Health post-NFL has been an issue and will continue to be. And not just knees/joints.
