It's been four days since the first set of College Football Playoff Rankings were announced, and Saturday's results will surely flip the next edition on its side.

With four top-15 teams losing before the night games even started, there'll surely be major changes awaiting next week.

Here are takeaways from Saturday's most noteworthy results.

Alabama wins ugly

The committee might be wrong about Alabama.

Just four days after the one-loss Crimson Tide jumped all undefeated teams in the country outside of Georgia to grab the No. 2 spot in the CFP rankings, undermanned LSU nearly handed Nick Saban's outfit its second defeat of the season. Alabama's defense held strong at the end of the contest to preserve the victory, but a very underwhelming performance might sway the committee's decision-making come Tuesday.

The biggest surprise of the night was the struggles of the Crimson Tide's powerful offense. Alabama entered play as the country's second-ranked attack, while LSU's defense ranked 93rd. The Tigers negated the running game to hold the Tide to a combined six yards on the ground.

The Crimson Tide have a comfortable non-conference matchup with New Mexico State next week to get things right, but it'll be very interesting to see what the committee does after this surprising display.

Oregon seizes opportunity on road

Alabama's struggles in a narrow win over LSU and Michigan's State's loss to Purdue could very well see No. 4 Oregon move to No. 2 in Tuesday's CFP Rankings. The Ducks pitched a perfect road game Saturday, riding their dominant defense and running game to a 26-16 win over Pac-12 North rival Washington in Seattle.

Travis Dye torched the Huskies' defense for 211 yards rushing and a score as Oregon piled up over 300 yards total on the ground. Additionally, the Ducks' defense held Washington to a paltry 166 yards total in the victory.

After three straight one-possession games on the schedule, the Ducks have now created some separation in the Pac-12 with two consecutive double-digit victories. An after-dark home affair against Washington State awaits next week.

Purdue, the unranked assassin

For the second time this season, unranked Purdue took down a top-three opponent in comfortable fashion. First, it was No. 2 Iowa falling at home to the Boilermakers; Saturday, it was No. 3 Michigan State's turn. Aidan O'Connell threw all over the Spartans for 539 yards passing in the 40-29 win in West Lafayette, Indiana.

It wasn't the first time Purdue ruined an undefeated season for Michigan State. The exact same result occurred the last time the Spartans entered a contest versus the Boilermakers in the same situation they found themselves in Saturday.

Purdue now has 17 wins as an unranked team over a top-five opponent in program history. That's the most all time in the FBS, cementing its status as an unranked assassin. As for Michigan State? While the loss hurts its CFP chances, the Spartans still stand a great shot at the playoff if they can win out and take down Ohio State in two weeks.

The ACC is toast

Its hopes were hanging by a thread to begin with, but it's now safe to eliminate the ACC from CFP contention. Despite coming into the day undefeated at 8-0, Wake Forest barely cracked the top 10 in the first CFP rankings. North Carolina entered play Saturday sitting just 4-4 on the season but found itself as slight favorites over the Demon Deacons.

Wake Forest looked like a powerhouse for a large portion of Saturday's contest, building an 18-point third-quarter lead thanks to its explosive offense. Unfortunately for Dave Clawson's outfit, the Tar Heels ripped off an incredible 31-10 run to close the game and claim a three-point win.

While the loss is a death knell to the team's CFP hopes, there's still plenty at stake for the Demon Deacons. The school has won just one ACC title in football and has only one season with double-digit wins in the 114-year history of the program. Both are attainable with a strong finish to the campaign.
