GIE projection: San Diego State by about one · Boise State 36th, San Diego State 55th.
Rivalries don't disappear when conferences reshuffle. Sometimes they just get new stakes.
San Diego State at Boise State used to be a game that decided the Mountain West. Now both programs are in the rebuilt Pac-12, and the same rivalry decides positioning in a brand-new league instead. The history is intact; the context is fresh. And the model projects it inside a single point.
This is the second bookend of our realignment thread — the league game that closes the loop the Boise-Washington State matchup opened earlier in the series. It carries the same trench note, too. Boise State's fronts added roughly 12.5 pounds of average mass across the offensive and defensive lines year over year in our roster data, one of the biggest such gains in the sport. In a game GIE calls a one-point margin, a physically bigger line is precisely the kind of hidden edge that decides it. Boise's rebuilt front now averages about 295 pounds a man to San Diego State's 291 — another reason a game projected inside a point may come down to the line. Watch the trenches: that's where a coin flip like this usually tips.
An old feud, new stakes, a one-point projection, and a physical question at the line. That's a November Sunday worth your time.
