Value Over Replacement (VOR) shows how much better a player was than the man a team could find to replace him. Each season stands alone.

100 is replacement level. We set that line the same way at every position. Take the players who got the most snaps. Two of every three sit above 100, and one sits below.

Every 30 points is one full step away from the pack. That step is the same size for a guard as for a quarterback. So you can put a corner next to a passer and compare them fairly. Small samples get pulled toward average, so a hot month does not pass for a great year.
