Every so often, an NFL game develops into a fantasy football goldmine.
For example, the New Orleans Saints beat the New York Giants, 52-49 on November 1, 2015. Six players had at least 60 receiving yards and one touchdown, and that doesn't even include the Giants' Dwayne Harris, who caught two touchdown passes.
If you have exposure to a similar game in a given week, then chances are you're picking up the fantasy win. If you're out of luck and your opponent has players from that one, then you have next to no shot.
