I’m no expert, and it’s certainly a complex model. As has been mentioned elsewhere, I think some level of preseason rankings is still baked in although I’m guessing that influence is phasing out if it’s not already completely phased out. My guess is the soft SOS in the preseason isn’t helping either (it’s not hurting, of course. But it’s not boosting either). Overall, NU has a SOS in the 100s so far, so that’s probably part of why the ranking is in the 50s despite the good record to start.
Pitt is ranked 78, so losing that one probably drags a bit. MSU melting down isn’t helping either, since they’re 0-3 in conference and down to 48 in the rankings. IU is winless in conference too and sinking so that’s not helping either. Go figure, the Hoosiers and Spartans are dragging NU down; if that isn’t 2020 in a nutshell....
If either of those teams straighten things out and go on a run, that will boost NU too. The model likes big margin of victory and road wins, too. So go blow out Iowa and then win at Michigan this week!
