College football rankings: Ohio State ranked No. 5 in Coaches Poll, 7 in the final regular season AP Top 25

Ohio State had the week off as Michigan State and Iowa battled for the Big Ten Championship, where the Spartans came out on top after a hard fought game that felt like a bowl game.

Clemson, Alabama, Oklahoma, and Michigan State appeared at the top of the AP Top 25 as you would expect, after the Tigers, Crimson Tide, and Spartans won their respective conference championships Saturday. Iowa, who lost that classic title bout against Sparty, finishes one spot higher in the AP than the Buckeyes in what could be a preview of the final College Football Playoff rankings.

The Coaches Poll Top 25 told a different story with Oklahoma over Michigan State and Ohio State considerably above Iowa. Stanford was also ranked higher than the Hawkeyes.

North Carolina dropped in both polls as a result of their loss against Clemson, but not without some controversy, as the Tar Heels were called for offsides on an onside kick that they recovered, when it appeared that they were in fact onside.

The Northwestern Wildcats appeared ahead of Michigan this week, coming in at No. 12 and No. 17 respectively in both.
