Projected vs. what happened

What we published before kickoff: the pick, the matchups and every stat as it stood going in.
How we picked it
Three ratings look at a team in three different ways. The numbers' pick is the team at least two of them favor.
Where the game is won
SP+ and PRIME take Northwestern, but Elo has Iowa. Northwestern's best matchup is its passing game, 15th in EPA per pass, against Iowa's pass defense at 109th. Iowa's way back in is its pass protection, 8th in sacks allowed per dropback, against Northwestern's pass rush at 113th.
Each row puts one team's unit against the unit it faces, by national rank out of all FBS teams. An edge is a gap of 25 spots or more.
Injuries and availability
Statuses come from the conference availability reports and team news, as of the date shown. "Hasn't played" means a regular (the main passer, a quarter of the carries or 15% of the catches) with no pass, carry or catch in his team's last two games, from the play-by-play. That can be an injury, a benching or a suspension. Linemen and defenders don't show up in that check.
