The model is
not specifically a preseason one (it's a power ranking system like human polls, RPI, Sangarin, and KenPom),
but the article is (it also it titled "Why does BPI rate Marquette higher than Duke or Kentucky?", which means it actually answers your gripes). If you can't figure out the difference, then I'll have to retract my statement that you're better than to fall for bad arguments. The model updates throughout the season based on more and better data, and is used throughout the season, primarily around the NCAA Tournament (who should be in, seeding, predictions, toughest bracket, etc...). And just because a model has flaws does not mean the whole thing should be thrown out, but I suspect now that is an argument above your head so why even bother?
Also are you seriously trying to say that ESPN created BPI with the specific intent of damaging Kentucky's preseason ranking? Or purposefully "mis-weighted" it to harm Kentucky (or Duke, I guess)? That's one of the dumber things I've read on RR in a long time.
