PPR

Point Per Reception. Every catch a receiver makes adds 1 point. Half-PPR = 0.5 per catch. Standard = 0.

ADP

Average Draft Position. The round and pick at which a player is typically drafted across all leagues.

Flex

A roster slot that can hold a RB, WR, or TE (sometimes QB in Superflex leagues).

Bye Week

Each NFL team has one week off during the regular season. Players on bye that week earn ZERO points.

Snake Draft

Each round reverses pick order. R1: 1→12. R2: 12→1. Designed to balance the advantage of having the first overall pick.

Handcuff

The backup running back for one of your starting RBs. Insurance for your top picks.
