Actually 2014 was one of the most flat years in distribution so there's not an obvious trend. The SD calculation normalizes for the size of the pool of teams--it should be the same regardless of whether there are 100 or 10,000 teams. The difference in the distribution is really driven by the nature of the game.

See my points above: It's not only lack of defense but the particular difficulty of gaining the highest point activities. There's been posts on that issue in other threads.
