Tiers are an alternate form of rankings that stresses the big picture rather than parsing the details. Alike players are grouped 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 shouldn't be your highest priority in the early rounds, but there comes a point where you can't afford to wait anymore.
