What a hit is
A hit is a top-12 or top-24 finish at the position within the prospect's first seasons, the window a dynasty manager actually holds a rookie before deciding to keep or sell. Both thresholds are shown because they answer different questions: top-24 is a startable asset, top-12 is a difference maker.
How comparables are grouped
Prospects are grouped by the signals that have historically predicted outcomes — NFL draft capital first, then position and the age-adjusted production profile. The hit rate for a group is simply the share of past prospects in that group who reached the threshold, so a first-round running back and a fourth-round receiver show very different base rates before any scouting is applied.
Base rates are deliberately blunt. They tell you the odds for the type of prospect, not for the person; the creators' rookie rankings are where the individual case is argued, and the two views are meant to be read together.
Using it in a rookie draft
The practical use is pick-to-pick comparison: when two prospects sit close in the rankings, the one from the higher-hit-rate group is the safer pick and the other is the higher-variance one. Combined with the rookie pick values in the trade calculator, it also tells you whether a pick is worth more as a pick or as the player you would take with it.
