Fantasy football has become a billion dollar industry and is one of the primary drivers keeping the NFL as America’s obsession. Daily Fantasy Sports (DFS) sites like DraftKings and FanDuel have taken the concept and distilled it into small doses of weekly competition. If you haven’t played DFS before, it’s fairly straightforward: all available players have an assigned salary and you have a salary cap – select players to fill your roster, while remaining under your salary cap. The players’ real life performance determines the score they earn for your team. You compete against others and the highest scores win.
