Watch a major college game, and the action gets weird. You immediately see plays that simply can't happen in a pro game. At the subdivision and Division II tiers, things get stranger still. And by the time you hit Division III, you begin to see football games that are more philosophical than technical. With no athletic scholarships and extremely limited resources, football becomes a game in which the system matters more than the play calling or the personnel. The polarities become acute. This is where you find the most extreme versions of contemporary football: This is where you find teams that still live in the 1950s and teams trying to play basketball on grass. This is the level where football changes — and also where it doesn't change at all.
