You have no idea what you are talking about, which should be so incredibly simple that I will never understand how you can't grasp it.
...except his answer is exactly correct, but I'm the one calling names, in your mind.
Both KenPom and NET are used by the Selection Committee for seeding and field selection. I have always had a problem with the "black box" nature of these models, and it looks like there are problems with them. 2 that come to mind are:
1) There is some kind of implicit bias in the model based on the opening published results that never gets fully washed out as the season goes on. While it is normal to have a model mute new outlier information to keep the model from getting too volatile in the beginning of its use, the projected starting point should be completely removed by some point, and it is not clear that is happening.
2) The model over-weights immaterial outlier events. This is a flaw in many models. A 50 point win over a really bad team should not move a model over a 25 point win over the same team.. The people running these models claim this is not happening, but they are black boxes, so who knows?
In this gem - you clearly demonstrate that YOU have no idea what you're talking about.
Kenpom and the NET are 2 completely different things. You and I agree (and have agreed in past) on the NET having black box stuff. It's not a good look, and breeds questions like the ones you have here.
Kenpom, however, is much much more open. It's basically 2 things:
1) Measuring offensive and defensive efficiency on per-possession basis
2) Measuring those measures against other teams measures, adjusting for factors like home/away, tempo (so number of possessions), etc.
It's also a PREDICTIVE measure, not a reactive one like polls (and probably NET, at least the black box piece of it). If Kenpom says that we are lower in overall ranking, it means that it's predicting a score and result where that team does better, all being relative.
Upcoming St John's game - perfect example. St John's is 16, and we're 34 right now. The NetRtg, which is what determines the ranking order, puts St John's about 5 net points ahead of us. Accounting for the fact we're playing at home, which eats into that 5 point margin, KenPom actually predicts a win for us.
Will outliers dictate swings in Kenpom? Sure, but nothing i would deem nefarious. Your "50 point win" scenario only really matters if it moves our per-possession numbers materially, which it might not at all.
