Tiers are an alternate form of rankings that stress the big picture rather than parsing the details. Alike players are bundled together at each position, thereby denoting the biggest drop-offs within the rankings. This way, you can control for position scarcity in the heat of the draft. The position nearing a drop-off is generally the one you'll want to target.   

Below are the shortstop tiers for 2023, depicting a position that's talent is largely concentrated in the middle. It stands to reason you'll have higher priorities early in the draft, but there comes a point where you can't afford to wait anymore.
