Higher is better on both sides — defence is flipped so the shape reads the same way. Percentiles are taken from the opponent-adjusted ratings, so a number earned against a hard schedule ranks above the same number earned against a soft one.

Opponent adjusted and shrunk toward last season — after 5 and 4 games, a rating is still part last year. On defence, negative is good.

06 / ELO

RatingBall StateNorthwesternGap
Elo, years of results10651720 +655

Worth 19.5 points of this projection. Elo carries what three games of play-by-play can't: years of results, so a team that has been bad for a decade isn't rated average in September.
