Michigan State is headed back to Indianapolis.
The Spartans left nothing to chance and clinched the Legends Division championship with their 30-6 win at Northwestern on Saturday.
Jeremy Langford had his second straight game of 150 yards rushing – and fifth straight 100-yard game.
Connor Cook threw for a career-high 287 yards on 15 of 23 passing with two touchdowns.
Northwestern got on the board first with a Jeff Budzien 27-yard field goal at the 7:55 mark of the first quarter.
The Spartans took the lead back on a 20-yard touchdown run by Jeremy Langford with 8:22 before the half. Langford accounted for 69 yards on the 80-yard drive and went over 1,000 yards for the season.
Michigan State took a 14-6 lead on the Spartans' longest play of the season. Connor Cook called an audible and threw a wobbly fade down the sideline to Bennie Fowler, who caught it reaching back over the cornerback and ran it in 87 yards for the touchdown.
The Spartans got creative for another touchdown as Cook faked a handoff to Langford and the reverse to Fowler and threw a strike to Josiah Price for a 15-yard touchdown. Geiger's extra point was blocked, leaving MSU with a 23-6 lead.
Cook was 5 of 6 for 81 yards on the drive, with big throws to Keith Mumphery for 20 yards and a checkdown to Langford for 24.
After a Kurtis Drummond interception, Langford took it to the house almost untouched from 37 yards out for a 30-6 lead.
