How the College Basketball Power Rankings Work

Every Division I men's team, ordered by computer ratings of how good it is rather than by a poll.

How It Works

The order is Bart Torvik's T-Rank. Once ESPN's BPI (Basketball Power Index) rates the current season, the order is the average of the two ranks; until then last season's final BPI sits at the far end of the table as context.

Before tip-off T-Rank is a preseason projection from returning players, recruits and transfers. Once games are played the same numbers become the live ratings.

The women's rankings use T-Rank's order alone (ESPN publishes no full women's BPI), with the women's AP poll beside it.

Proj W-L is T-Rank's projected final record. AdjOE and AdjDE are points scored and allowed per 100 possessions against an average team (adjusted offense and defense: high is good on offense, low on defense). Barthag is the chance of beating an average team on a neutral floor. Move is places climbed since an earlier day's order, and AP is the human poll once it has a ballot for this season. The top 25 are shaded.

Keep in Mind

It rates how good a team is, not its tournament rรฉsumรฉ: that is the bracketology page's question. A school whose name the sources spell differently can miss its BPI, and shows a dash.

When It Updates

Twice a day all year, as T-Rank is refreshed.

For the Curious

T-Rank is one of the two rating sources the bracketology model trains on. Averaging two independent ratings smooths out the quirks of either one, the same reason the fantasy draft board blends several sites' rankings.
