What the hell is up with the BPI?

Michigan basketball is currently ranked 4th in Bart Torvik's rankings, and 6th in kenpom. So what the hell is up with BPI?

We're ranked 15th, one spot behind (wait for it...) Villanova. (To be fair, we're second in ESPN's "resume" computer ranking. But I think maybe they're overvaluing preseason expectations if they've got us ranked behind a team we beat by 20+ on the road who also lost to Furman).

Yeah, all of ESPN's fancystats are terrible. I'm convinced they do it on purpose so the Mike Golics of the world can rail against them and how nerds are ruining sports.

They probably are overrating preseason expectations. However, SOR is based on BPI, so we wouldn't be as high in that if BPI ranked the other teams where they belong. This early in the season, BPI isn't every going to be very accurate, but SOR can be, so maybe that's what they are going for.

I don't think that's the case.  It looks like it is essentially just calculating points per possession (for and against), taking into account the strength of the team they played (among other factors), and then adding together a score based on how well their points per possession look offensively and defensively.  It does not take into account the actual wins and losses that take place.

So a team like UNC still has ridiculously high points per possession and looks good in this type of ranking.

small sample size.  torvick and kenpom use data from last year.  i'm not sure if BPI does.  by the end of the year, BPI, torvick and kenpom will all be about the same.  this is nothing to get worked up over.

BPIs failing is that it relies too heavily on ESPN recruiting rankings for its preseason projections.  I think overall it’s okay when it catches up, but for a team that lost a lot of production from the prior year, and was replacing it with primarily unranked 3 and 4-stars that had little or no college performance to project from, it is going to doubt us until we have even more of the season behind us.

The one thing the NET does is it takes away the preseason  and last seasons rankings and only looks at this years body of work.  That is why you have a Belmont and Loyola Marymount toward the top. I like that it takes out any of the bias.

This doesn't bother me as much as the fact that the selection committee team sheets still include some bullshit metric called KPI, developed by a former MSU student manager, that has consistently done a terrible job of seeding teams in its history. And this thing is specifically highlighted (along with RPI, KenPom, BPI and others) on each school's official team sheet.

(KPI had Michigan a 5 and was the only entry in the Bracket Matrix that had them anything other than a 3 or a 4.)

Description from ESPN site...the BPI is a ranking “that is meant to be the best predictor of performance going forward”

meant to be, but clearly NOT, a predictor of fuck all
