AP Top 25 Takeaways: Oklahoma upset; Miami over FSU, finally

Four of the top five teams in the country kicked off their games at noon Eastern on Saturday, which suggests that all were expected to roll.
No. 2 Clemson, No. 4 Penn State and No. 5 Georgia all did just that. Then there was No. 3 Oklahoma. The Sooners and Iowa State provided some early drama and the first really big upset of the season. Then No. 13 Miami and Florida State played another classic, with the Hurricanes finally getting some satisfaction in the series.
Thoughts, takedowns and takeaways from week six of the college football season.
1. The mental gymnastics that begin after an upset in college football can strain the brain. Does Oklahoma’s loss kill the Big 12’s College Football Playoff hopes? And what does it mean for No. 10 Ohio State? The Buckeyes lost decisively at home to the Sooners.
2. Too much ball left to play to make any kind of definitive statement, but a reminder: Ohio State lost at home to a Virginia Tech team that went 6-6 in 2014 and went on to win the national championship. Clemson lost at home to a Pitt team that won eight games before winning it all last season.
3. It’s a bad loss for Oklahoma — the first loss by a top-10 team to an unranked team this season — but not necessarily a deal-breaker when it comes to making the playoff.
4. As for Iowa State, the Cyclones showed a lot of fight last season, even while going 3-9 in year one under coach Matt Campbell. Iowa State only plays three more home games, but this looks like a team that can get bowl eligible — which hasn’t happened in Ames since 2012.
5. Campbell seemed like a home run hire for Iowa State and so far still very promising.
6. Iowa State quarterback-turned-linebacker-turned-back-to-quarterback Joel Lanning had a performance Gordie Lockbaum would have been proud of.
7. Google Gordie Lockbaum. We’ll wait.
8. No. 8 TCU is the lone remaining unbeaten team in the Big 12 after beating No. 23 West Virginia , but it certainly feels as if the Big 12 could get messy with not a lot of separation between about six teams.
9. West Virginia quarterback Will Grier came up on the short end of another close game against a good team (Virginia Tech in the opener), but the Florida transfer’s play has been even better than advertised this season. SoCal QBs San Darnold and Josh Rosen get most of the hype when it comes to the NFL draft, but Grier could be a first-rounder, too — if he decides to leave school early.
10. Now that Miami has gotten over that Florida State hurdle and snapped a seven-game losing streak in the series , the ‘Canes could be ready to roll. Miami plays only two more road games the rest of the way, getting No. 21 Notre Dame and No. 16 Virginia Tech at home.
11. Florida State is the best 1-3 team in the country. Maybe the best 1-3 college football team in recent memory. Surely, this is no consolation to ‘Noles fans.
12. Clemson lost Kelly Bryant to a sprained ankle in a routine victory against Wake Forest . The Tigers play at Syracuse next Friday so if Bryant needs a game off that should be a good time to get him one. You would think Clemson should be in good hands with either five-star freshman Hunter Johnson and redshirt freshman Zerrick Cooper. And then the Tigers get a week off.
13. The biggest remaining game in the Atlantic Coast Conference: Clemson at No. 24 North Carolina State on Nov. 4.
14. Saquon Barley was less than Heisman-like against Northwestern , but nothing so bad it will hurt him in the long run. After a week off, Penn State plays No. 7 Michigan, No. 10 Ohio State and Michigan State in consecutive weeks. That will determine whether Barkley wins the Heisman.
15. Though Baker Mayfield not being able to come through in the clutch for Oklahoma certainly didn’t hurt the Barkley campaign.
16. Georgia ran 423 yards in throttling Vanderbilt . For comparisons sake, Alabama had 496 yards rushing against Vanderbilt and won 59-0. It certainly looks as if the Tide and the Bulldogs are heading for what could be the first really competitive and consequential SEC title game since 2012 — when Alabama beat Georgia with a late defensive stand.
17. LSU coach Ed Orgeron gets to step off the SEC grill this week . C’mon down, Arkansas coach Bret Bielema, whose team got crushed by South Carolina to fall to 0-3 in the SEC. Gamecocks scored three defensive touchdowns.
18. Arkansas’ next two games: at No. 1 Alabama and home for Auburn. Bielema could really put athletic director Jeff Long’s loyalty and that huge buyout to the test .
19. Remember, Jim McElwain was hired to fix Florida’s offense.
20. Now things get interesting for Notre Dame, 5-1 heading into its week off before hosting No. 14 Southern California in what could be playoff eliminator. The Irish have held each of their first six opponents to no more than 20 points . The last time that happened was 2012, when Notre Dame played for the national title.
21. USC had a routine bounce-back game against Oregon State with Darnold tossing three TD passes. But while the Fighting Irish are getting healthy — most notably quarterback Brandon Wimbush — the Trojans will be playing a Utah team that is usually a handful next week.
22. No. 10 Ohio State concluded the plundering-the-villages portion of its schedule by outgaining Maryland 584-66 . Final tally: Ohio State 210, Army/Rutgers/UNLV/Maryland 42.
23. The Buckeyes go to Nebraska next week, and maybe we’ll get a better read on whether that offense is really fixed. That’s the last test run before Penn State comes to town on Oct. 28.
24. Most surprising start? Virginia is 4-1 under Bronco Mendenhall after winning two in his debut season last year.
25. Under the radar: Tulane beat Tulsa 62-28 in a game that kickoff around brunch time to get it done before Hurricane Nate hit New Orleans. The Green Wave (3-2) are halfway to bowl eligibility after reaching the 50-point mark against an FBS team for the first time since 2004. Second-year coach Willie Fritz is doing an impressive job with a program that has been down for a long time.
