SPORT: NFL

The NFL is the most efficiently priced market in American sports, and that is a direct consequence of how much money runs through it. Sixteen games a week, a full week of public attention on each one, and the largest limits on the board mean errors get corrected fast. Edge does not come from picking winners more often than the market. It comes from knowing which parts of an NFL number are sharp and which parts are a concession to predictable betting behavior.

Two structural features do most of the work. Key numbers, because football scores cluster on 3 and 7, so half a point around those figures is worth far more than half a point anywhere else. And the injury cycle, because the practice-report rhythm from Wednesday to Sunday means the same information reaches the market at predictable times. This track works through both, then adds the situational, weather, and playoff patterns that recur every season.
