The final slate of games in October set the perfect stage for the first round of College Football Playoff rankings this week. There are five undefeated Power Five teams, two of whom play each other, so November is set to be an epic month for the sport once again. Here is a look back at what happened this past week on the field.

1. Oklahoma suffers the weekend’s biggest upset loss

Congratulations to the Kansas Jayhawks for scoring a gigantic upset win. Lance Leipold is one of the best coaches in college football, and he’s got Kansas rolling at 6-2 now. Brent Venables still has OU in control of its own destiny to win the league thanks to that win over the Texas Longhorns, but there’s much less room for error.

2. Big 12 in danger of missing College Football Playoff

With OU’s loss coming a couple weeks after beating Texas, the Big 12 becomes the first Power Five conference to have no undefeated teams. You can say that’s because of how difficult the league may be this year, and there could be some merit to that, but the fact of the matter is with the way the rankings are now, it’s the one league where nobody controls their destiny to reach the CFP.

3. Oregon gets best win of College Football Playoff contenders

Right now, the Ducks are the only school who have control of their own destiny in the College Football Playoff race with a loss. If they win out, they will get a rematch with the one team to beat them, the Washington Huskies. Over the weekend, they dominated the Utah Utes 35-6 in arguably the most impressive win of any team this year.

4. Multiple CFP contenders suffer second loss in wild upsets

Utah joined a slew of CFP contenders to lose their second game, but they were the only ones to fall to another contender. The Oregon State Beavers suffered a shocking upset loss to the Arizona Wildcats on the road, and the North Carolina Tar Heels suffered a second straight upset loss, falling to the Georgia Tech Yellow Jackets.

5. Georgia and Michigan STILL have proven nothing

Two of the undefeated teams in college football, the Georgia Bulldogs and Michigan Wolverines, have still beaten nobody. UGA beat a bad Florida Gators team over the weekend, and Jim Harbaugh’s team, battling major allegations of spying at the moment, didn’t have a game over the weekend. They control their own destiny, but they have a lot to prove.

6. Washington survives, OSU wins, FSU dominates

We mentioned Washington earlier, and they had to hold off the Stanford Cardinal. Meanwhile, the Ohio State Buckeyes scored a 24-10 win over the Wisconsin Badgers, which continues their mantra of winning ugly, but their resume is still impressive. With the Florida State Seminoles blowing out the Wake Forest Demon Deacons, they could be the best team right now.

7. Louisville, Ole Miss won’t go away

We mentioned Oregon, Texas and Penn State. The Alabama Crimson Tide and Missouri Tigers had byes this week. That left the Louisville Cardinals and Ole Miss Rebels as other one-loss teams. Ole Miss did what it should’ve done against the Vanderbilt Commodores, but Louisville dominated the Duke Blue Devils, a top 25 team, and controls its own destiny in the ACC. Both could shake up the CFP race.

8. Three undefeated Group of Five teams remain

Could this be another year a Group of Five team sneaks into a bowl game? The James Madison Dukes can’t, as they still aren’t postseason eligible due to their new status as an FBS program. However, the Liberty Flames and Air Force Falcons are also both undefeated. It doesn’t seem likely either goes, but if more upsets happen, watch out.
