Whenever it's supposed to be a "down week" in college football, it is anything but a down week. It happens over and over again, no matter the season, and Week 4 of the 2021 campaign was no different. This week brought us several massive upsets, contenders continuing to dominate and style points that were either gained or lost in the race to make the College Football Playoff.

No. 1 Alabama cruised to a win over Southern Miss, as did No. 2 Georgia on the road at Vanderbilt. Other contenders ... not so much. No. 9 Clemson suffered its second loss of the season in overtime to NC State. No. 4 Oklahoma escaped the clutches of West Virginia on a walk-off field goal. No. 7 Texas A&M fell to No. 16 Arkansas in the biggest game of the SEC West season so far.

It's time to hand out some grades to the College Football Playoff contenders, listed based on Saturday morning's odds from Caesars Sportsbook. The 16 teams below are not technically the only ones who could make the CFP this season, but it's where we focus our attention as we await others to make jumps into the top of the college football rankings.

As such, expect to see the teams in this column adjust weekly and eventually shorten as the season goes on. You can also check out our projected college football rankings before the new AP Top 25 comes out Sunday.
