Big Ten football power rankings after Week 6: Separation at the top

We have now seen six weeks pass by quickly in college football, and with it separation at the top. Here's the latest Big Ten football power rankings.

Five weeks of the college football season are now complete, and that means we're starting to see some separation among some of the pretenders (Clemson) and the contenders (Ohio State and Oregon). What we thought we knew at the beginning of the season was fantasy, and now we are dealing with reality, not only across the country, but in the Big Ten as well.

Now that we've had a few weeks to assess what's going on in the conference, we feel like we have a little better handle on what teams are playing well -- maybe as we expected -- and which ones might be in for a long, long season. We're even starting to have some surprise teams emerge (hello, Indiana again).

And so, we share with you our weekly Big Ten football power rankings. Some of the teams had an off week before their conference competition begins, so more to come. It still looks like Ohio State and Oregon, and might be the class of the league after Penn State went down unexpectedly and unexcusably to UCLA, but there are still others like Iowa, Michigan, and USC that could throw a wrench into things.

Here's a look at our Big Ten football power rankings following Week 6. We start from No. 18 and make our way down to No. 1 as usual.

No. 18 - Purdue Boilermakers (2-3, 0-2 Big Ten)

LastWeek's Result: Lost 43-27 vs. Illinois

Last Week Ranking: 15 ⇩ (down three spots)

Next Game: at Minnesota

What goes into the ranking

Purdue didn't have a horrible showing against Illinois, but you can't get beat like that at home. The defense can't seem to stop running water in a faucet at this point, and that's both a plumber and the team's big problem. Combine that with UCLA doing some astonishing things to move up these power rankings and, well -- here you are, Pur-don't.

No. 17 - Wisconsin Badgers (2-3, 0-2 Big Ten)

Last Week's Result: Lost 24-10 at Michigan

Last Week Ranking: 16 ⇩ (down one spot)

Next Game: vs. Iowa

What goes into the ranking

This might be the worst Wisconsin team we've seen in a very long time. The defense kept the Badgers in it against Michigan in the Big House for a half, but the offense was and is abysmal. This looks like a team that will be sitting home for the holidays, and if things continue this way, the program might be putting a bow on a new head coach.

No. 16 - UCLA Bruins (1-4, 1-1 Big Ten)

Last Week's Result: Won 42-37 vs. Penn State

Last Week Ranking: 18 ⇧ (up two spots)

Next Game: at Michigan State

What goes into the ranking

OK, we see you, UCLA. Is something BRUIN in Westwood? If quarterback Nico Iamaleava plays like he did against Penn State, there could be some problems for the remainder of the league. One week does not a turnaround make, but the Bruins did enough against a good team to move up the rankings for now. Was it lightning in a bottle, or is a storm coming?

No. 15 - Northwestern Wildcats (3-2, 1-1 Big Ten)

LastGame Result: Won 42-7 vs. UL-Monroe

Last Week Ranking: 17 ⇧ (up two spots)

Next Game: at Penn State

What goes into the ranking

We really didn't learn too much from the Wildcats' win over an underwhelming opponent other than they put a real, live offense out on the field for once. Who knows? How in the world did the Northwestern defense hold UCLA to 14 points, and Penn State couldn't keep it to under 40? Paging Jim Knowles.

No. 14 - Michigan State Spartans (3-2, 0-2 Big Ten)

LastWeek's Result: Lost 38-27 at Nebraska

Last Week Ranking: 13 ⇩ (down one spot)

Next Game: vs. UCLA

What goes into the ranking

There's no doubt the Spartans are a more competitive bunch this season, but it's one thing to be more competitive; it's another to start notching wins instead of losses. There are no participation trophies handed out in the halls of the Big Ten offices, so we need to see Michigan State start to close games.

No. 14 - Rutgers Scarlet Knights (3-2, 0-2 Big Ten)

Rutgers Head Coach, Greg Schiano watches his Scarlet Knights, Thursday, August 28, 2025.

Last Week's Result: Off

Last Week Ranking: 14 ⇧ (up one spot)

Next Game: at Washington

What goes into the ranking

Hey, look, it's Rutgers. The Scarlet Knights were on an off week, so we learned as much about them as we do when we see them play an actual American football game. Who really knows where this team slots right now? Yes, they are well coached, and we'll get to see more when they traverse the entire North American continent to play Washington. Get those air miles ...

No. 12 - Minnesota Golden Gophers (3-2, 1-1 Big Ten)

LastWeek's Result: Lost 42-3 at Ohio State

Last Week Ranking: 12 ⇔ (no change)

Next Game: vs. Purdue

What goes into the ranking

You kind of know what you are going to get with Minnesota under P.J. Fleck. The Gophers will play solidly and beat average teams more often than not, but get publicly flogged by the really good teams of the league. Ohio State got out the whooping stick, and I don't know if I've ever seen the Minnesota head coach so dejected and lost for answers. We'll root for the Gophers to sneak into a bowl game again, and that's about the expectation these days.

No. 11 - Maryland Terrapins (4-1, 1-1 Big Ten)

LastWeek's Result: Lost 24-20 vs. Washington

Last Week Ranking: 11 ⇔ (no change)

Next Game: vs. Nebraska

What goes into the ranking

Maryland came achingly close to getting a big win against a very good Washington team, but then it remembered it was Maryland in a Big Ten game. The Terps generally buy the winning optional package when the Big Ten starts, and we'll see if that's the case as 2025 continues on. It was a promising game, but a defeat nonetheless.

No. 10 - Iowa Hawkeyes (3-2, 1-1 Big Ten)

Iowa Hawkeyes quarterback Hank Brown (9) lines up under center against the Albany Great Danes Aug. 30, 2025 at Kinnick Stadium in Iowa City, Iowa.

LastWeek's Result: Off

Last Week Ranking: 10 ⇔ (no change)

Next Game: at Wisconsin

What goes into the ranking

Iowa does what Iowa does, and we were beginning to wonder if the offense would score more points sitting on the couch this week than when it suits up for a game. As always, the defense seems to be great, but that will only carry the Hawkeyes so far. Next up is a chance to win the Heartland Trophy. It's going to be a punter's dream Saturday.

No. 9 - USC Trojans (4-1, 1-1 Big Ten)

LastGame Result: Off

Last Week Ranking: 4 ⇩ (down five spots)

Next Game: vs. Michigan

What goes into the ranking

USC was also off this past week, so hopefully it had a chance to examine the defense. The offense behind quarterback Jayden Maiva can keep the Trojans in almost any game; it'll just boil down to whether or not the defense gets off the bus against the better teams.

No. 8 - Penn State Nittany Lions (3-2, 1-2 Big Ten)

LastGame Result: Lost 42-37 at UCLA

Last Week Ranking: 3 ⇩ (down five spots)

Next Game: vs. Northwestern

What goes into the ranking

What happened in the Rose Bowl on Saturday is one of the most shocking results I've seen in a long, long time, and now the margin for error is razor thin, and maybe gone for the Nittany Lions with the way Ohio State and Oregon are playing. You have to wonder if former Ohio State defensive coordinator Jim Knowles is having buyer's remorse and seeing the colors of Scarlet and Gray in his nightmares. The defense on Saturday made UCLA look like the second coming of Pete Carroll's USC Trojan offenses.

No. 7 - Illinois Fighting Illini (5-1, 2-1 Big Ten)

Last Week's Result: Won 43-27 at Purdue

Last Week Ranking: 8 ⇧ (up one spot)

Next Game: vs. Ohio State

What goes into the ranking

Illinois has looked so good in all of the games that it didn't give up 63 points. Seriously, I've heard of outliers, but the Indiana game may have been dropped down to Earth by an alien spacecraft. As bad as that game was, the Illini now have a chance to show the world it just didn't show up because No. 1 Ohio State comes to town this coming weekend.

No. 6 - Nebraska Cornhuskers (4-1, 1-1 Big Ten)

LastWeek's Result: Won 38-27 vs. Michigan State

Last Week Ranking: 7 ⇧ (up one spot)

Next Game: at Maryland

What goes into the ranking

Nebraska might be better than this ranking, but we just don't know. Dylan Raiola at quarterback seems to be settling down and putting this team in a position to be a player in the Big Ten race, but the loss to Michigan is going to sting, and the trip to Maryland will not be easy as long as the Terps think of it as a nonconference game. It would also help if it isn't a close game because Nebraska has yet to solve that crossword puzzle.

No. 5 - Washington Huskies (4-1, 1-1 Big Ten)

LastGame Result: Won 24-20 at Maryland

Last Week Ranking: 6 ⇧ (up one spot)

Next Game: vs. Rutgers

What goes into the ranking

After watching Washington last week against Ohio State, I was convinced that the Huskies were one of the better teams in the Big Ten. The first half of the Maryland game had me re-thinking that, but then Washington came back and won a tough contest against a team that might be better than we think -- and on the road. It was a good bounce back and showed resiliency for a team that still might have a lot ahead of it.

No. 4 - Michigan Wolverines (4-1, 1-1 Big Ten)

Michigan quarterback Bryce Underwood (19) makes a pass against running back Justice Haynes (22) against New Mexico during the second half at Michigan Stadium in Ann Arbor on Saturday, August 30, 2025.

LastWeek's Result: Won 24-10 vs. Wisconsin

Last Week Ranking: 5 ⇧ (up one spot)

Next Game: at USC

What goes into the ranking

Michigan won again, but we still can't get that very dysmal performance against Oklahoma out of our noggins. It seems like Bryce Underwood will be a better quarterback at the end of the year, and that could be a problem for -- ahem, Ohio State. Right now, though, Michigan's best win is a close one against Nebraska, and we're still not sure what kind of team the 'Huskers are just yet.

No. 3 - Indiana Hoosiers (5-0, 2-0 Big Ten)

Sep 20, 2025; Bloomington, Indiana, USA; Indiana Hoosiers head coach Curt Cignetti watches his team during the second half against the Illinois Fighting Illini at Memorial Stadium. Mandatory Credit: Robert Goddin-Imagn Images

LastWeek's Result: Off

Last Week Ranking: 4 ⇧ (up one spot)

Next Game: at Oregon

What goes into the ranking

With Penn State's belly flop in the shallow end of the pool in Pasadena, it's a no-brainer that Indiana moves up to the No. 3 spot, and deservedly so. The Hoosiers have looked fantastic aside from the trip to Iowa, and even then, they were able to pull out a close one at the end in a hostile environment. The question is -- how big is the gap between the No. 3 team and the top two here?

No. 2 - Oregon Ducks (5-0, 2-0 Big Ten)

Oregon Ducks quarterback Dante Moore carries the ball as the Oregon Ducks host the Oregon State Beavers Sept. 20, 2025, at Autzen Stadium in Eugene, Oregon.

LastWeek's Result: Off

Last Week Ranking: 3 ⇧ (up one spot)

Next Game: vs. Indiana

What goes into the ranking

You could make a case for Oregon being the top team in these rankings, but after Penn State's showing against UCLA, it does make you wonder just how impressive the win in Happy Valley will end up looking. Still, this is a good team with a good roster, a good coach, and a quarterback who can go out and win a matchup game when it matters.

No. 1 - Ohio State Buckeyes (5-0, 2-0 Big Ten)

Sep 13, 2025; Columbus, Ohio, USA; Ohio State Buckeyes quarterback Julian Sayin (10) reacts after the game against the Ohio Bobcats at Ohio Stadium. Mandatory Credit: Joseph Maiorana-Imagn Images

LastGame Result: Won 242-3 vs. Minnesota

Last Week Ranking: 1 ⇔ (no change)

Next Game: at Illinois

What went into the ranking

The Buckeyes looked awfully impressive against Minnesota and seem to be getting better by each passing week. The offense hasn't looked as explosive, but based on what we saw Saturday, it feels like it can turn the temperature up any time it wants. Oh, and the defense? Ridiculous. The silver bullets have only surrendered 25 points in five games. There's no better team in college football right now -- at least that's how it looks at the moment. A tricky game in Champaign is up next.
