Coaches

Every coach's record, accomplishment, and tournament performance measured against the same field.

A late-1970s handheld electronic basketball game in a scuffed old gold and black case, its small screen of red LED dots glowing, resting on a wooden table beside a bowl of pretzels. — Coaches, tabletop edition.

Tournament performance vs. seed, by coach

Field-context note: "expected wins" is the historical win rate for that seed line across the full NCAA tournament field, not a Purdue-specific baseline, so this measures whether a coach's teams over- or under-performed their seed relative to every other team that has held that seed.

Results above roster

A crude coaching-effect estimate: the season-over-season change in team rating that is not explained by the share of production returning from the prior roster. Labeled "crude" because it does not account for recruiting class quality, which this dataset does not have.
