Week 10 of the 2021 season features one key change compared to the weeks prior: the first College Football Playoff rankings are out, giving everyone in the list of 25 teams a better idea of where they stand.
For Michigan State, its placement at No. 3 puts it firmly in the race for one of the four spots. But a trip to West Lafayette could make that ranking short-lived; Purdue has already knocked off one top-10 team this season. Fellow undefeated program Wake Forest, at No. 9 in the playoff rankings, has some work to do, and can't afford a slip-up with a visit to Chapel Hill to face UNC.
