Season-long fantasy football tier projections for Wide Receivers focus on the probable outcomes for a player based on top-down production on a play basis and projected game script and then player opportunity production based on that team volume.
We can tweak volume and efficiency for a range of outcomes per player, but that is the simplest explanation of how the projection sauce is made.
While those projections give us a range of season-long production and have implications for listing players in a linear format (rankings) they fail to capture the overall weekly impact and pockets of production that are relevant to our weekly game of fantasy football.
While the rankings are more focused on a probable tally of season-long output for a week-to-week game, these tiers are based on how similarly players accrue their fantasy points and by the archetypes of players they are.
By doing this, these tiers will allow you to notice actionable gaps in player pricing per tier which in turn allows for arbitrage in your fantasy drafts.
While there is not a direct overlap to the individual player rankings, the order of these tiers is how I prioritize drafting the positions from an archetypical stance.
