This article attempts to highlight some of the best and worst matchups for wide receivers and tight ends each week. Using player tracking data from various sources (NFL.com, Pro Football Focus, ESPN, etc.) as well as reviews of recent trends, I look for situations to exploit or avoid when setting your weekly lineups. Given that this article is intended to help across all sites (both DFS and season-long), variations in pricing and scoring systems are not taken into account so obviously, the values could shift depending on where you are playing. The main intent of this article is simply to call out some players who could be significantly helped or hurt by their situations each week.
