Auction rooms misprice injury history in both directions

Draft and auction markets react to visible surgeries and ignore the accumulated wear that actually determines who is available.

Put a player with a recent, well-documented operation into an auction room and watch the price fall. Put in a player of the same age who has never been operated on but has played eleven straight seasons with a heavy minutes load and a couple of quiet strains a year, and the room bids him up. The second player is frequently the worse bet, and the market gets this wrong in a predictable direction, which is what makes it interesting.

The bias is about legibility. A surgery is an event with a date, a name and a public rehabilitation timeline. Accumulated load is not an event. It has no headline, does not appear in a summary, and shows up only as a slowly rising probability of soft-tissue absences that individually look like bad luck. Markets price events. They struggle with hazard rates.

There is a structural reason the mispricing persists rather than being arbitraged away. In auction formats, franchises bid under time pressure with limited independent medical access, often relying on the same public information everybody else has. In draft formats, teams do get thorough examinations, and there the bias flips: minor findings on a scan of a twenty-one-year-old, most of which are present in plenty of asymptomatic athletes, cause slides that cost players enormous guaranteed money.

So both formats are wrong, in opposite ways, for the same underlying reason. Whatever is measurable and named gets overweighted, and whatever is diffuse gets ignored.

A franchise with genuine edge would do the boring thing and build a minutes-and-recovery history model for every target, then bid against its own estimate of availability rather than against the room's reaction to a scan. A few do. Most spend their analytics budget on production rather than durability, which is strange when availability is a bigger driver of a season than any single skill.

If you want to find the underpriced player in the next auction, look for the one whose problem has already been cut out and repaired, and bid while everyone else is reading the word surgery.
