Tiers are a simple but effective way of plotting out a draft strategy that assures you won't fall behind at any position while maximizing your return on every pick. They serve an alternate form of rankings that groups players by expected level of production, denoting the points in the rankings where the most significant drop-offs occur. In the heat of a draft, you'll know which position to target by observing which one is closest to having its current tier depleted.
