Pro Football Reference’s Hall of Fame Monitor (HOFm) end-of-career score

A score of 100 is around the average modern-era NFL Hall of Fame inductee. A score of 80 or above means they're a good candidate to eventually get in, or they’re the highest-profile borderline candidates.

This market resolves to the player’s HOFm score, rounded to the nearest integer, at the beginning of the NFL season following the announcement of the player’s retirement or effective retirement (no longer actively seeking employment).

If a HOFm score for this player is not published at market close (for example, as of market creation, a score is only published for players with 50+ career games), this market will resolve N/A.
