Value Over Replacement (VOR) measures how much better a player is than a typical replacement-level player at their position — the kind of player any team could sign off the street or promote from their practice squad.

100 is replacement level. 150 means 50% better than replacement — a franchise-level player. Below 100 means below that bar. Because replacement level is position-specific, VOR lets you compare a dominant CB to an elite QB on the same scale.
