Fans swear big lines win games. They're half right — big-line teams do win more, but only because good programs recruit big linemen. Once we account for talent and last season, line size adds nothing to the prediction. Across 11 seasons, no measurable effect on margin.

Roster size is context. It isn't a forecast advantage.

A new coordinator feels like it should swing a game. Across 11 seasons, the change doesn't move the final margin beyond what the roster already tells us. Shown as context, not a factor in our number.

Run-heavy team meets a defense that can't stop the run — feels like extra points waiting. Across 7 seasons the matchup adds nothing beyond what the two ratings already say; if anything the point estimate leans the other way.
