Week 10 was survival Saturday for the top teams in college football, and the five undefeated contenders all passed in-conference tests to keep the all-important zero in the loss column ahead of Tuesday's College Football Playoff rankings.
They didn't all pass their tests with the same level of impressive play, though, as Ohio State trailed at halftime against Rutgers before pulling away down the stretch while Florida State seemed to sleepwalk for most of its game against Pittsburgh.
Michigan had little trouble with Purdue, but the wins that stood out the most were Georgia's victory over previously 12th-ranked Missouri and Washington prevailing against USC in a defense-optional showdown in the Pac-12.
