COLUMBUS, Ohio -- Fifteen undefeated teams remain from the Power Five conferences entering play this weekend, and 14 play Saturday, with only Texas A&M getting the week off.
Two of those undefeateds play each other, as No. 5 Utah and No. 23 Cal face off Saturday night as the last two perfect teams from the Pac-12.
Another seven face legitimate tests: Iowa at home against 4-1 Illinois; Clemson at home against 2-3 Georgia Tech; Oklahoma State on the road as an underdog at 3-1 West Virginia; TCU at 3-1 Kansas State; Florida at 4-1 Missouri; Florida State at home against 3-1 Miami; and Northwestern as a big underdog at 4-1 Michigan.
