Making those tough lineup decisions, week over week, can be the most challenging part of the fantasy football process. When you're torn between two similar players and simply don't know which of them to start, my advice is to start the player with the superior matchup.
Ah, but exactly how does one determine the best (and worst) weekly matchups?
The "Matchups Map" each week provides a schedule-independent method to evaluate positional matchups, ranking all 32 opposing defenses in order of most to least favorable for opposing players at all four skill positions (quarterback, running back, wide receiver and tight end). Instead of relying upon seasonal totals, in this space we calibrate points allowed data to show how each defense fared relative to the difficulty of the schedule that it has faced. This provides a fairer approach to judging the quality of individual matchups.
"Adj. FPA," or Adjusted Fantasy Points Allowed, reflects how far above or below players' weekly PPR fantasy point averages that defense has held opponents at that position. A positive number means that the matchup is favorable; a negative number means it is unfavorable. Additionally, remember that teams often use multiple running backs and wide receivers in a game, and these plus/minus averages cover all of a team's personnel at that position.
All data is from the past five weeks of NFL action.
Finally, a caveat: Matchups are only one ingredient in my rankings formula. Not every favorable matchup should be exploited, nor unfavorable matchup avoided. If you want my -- and ESPN fantasy staff's -- most complete source for whom to start and sit each week, consult our weekly rankings.
