Returning production

57% overall, ranked #44 nationally.

Offense 57% · Defense 58%

132 returning starts, 15 redshirt freshmen.

Two models, one slate. This report's schedule math projects 5.38 wins; Connelly's published model projects 5.4 (2.8 in conference) with a strength-of-schedule rank of #6. His model gives 44.5% odds of six-plus wins and 0.0% of eleven-plus. Two independent methods landing close together is corroboration, not confirmation — they share SP+ as an input.

How to read the margin column. It is the SP+ rating gap plus home field, in points — a positive number means the model favors Northwestern. Win percentage is that margin mapped through a logistic calibrated so a seven-point favorite wins about 70% of the time.

Method & Provenance

Sp 2026. Committed preseason SP+ snapshot data/external/cfbd_2026/sp_plus_2026.csv via cfb_model_lab.preseason.load_sp_plus; CFBD /ratings/sp returns zero rows for 2026.

Schedule. data/external/cfbd_2026/schedule_2026.csv (CFBD /games snapshot, regular season only).

Connelly. Bill Connelly ESPN+ 2026 conference previews extracted to data/external/connelly_*_2026/.

Projection Method. SP+ differential plus 2.5-point home field, mapped to win probability by a logistic with scale 8.0 (illustrative scale; not validated for this SP+ snapshot). Win distribution is an exact Poisson-binomial assuming independent games. Not a betting model and not the repo's StackedEnsemble forecast.

Lower Division. FCS/lower-division opponents absent from the FBS SP+ table are assigned a -25.0 rating placeholder.

Not betting advice. No market lines were pulled for this report and no edge is claimed. These are schedule-strength projections from public preseason ratings. If a real market exists, price it independently.
