It may be Sunday, but the stock market is open at Saturday Tradition.

This is your weekly recap of the Big Ten’s biggest movers in either direction each given week.

And since we want you to become informed investors, we won’t just recap the obvious — we’ll tell you whether this movement will be permanent, or just a temporary illusion.

Stock up

1. Kinnick Stadium

Iowa’s Kinnick Stadium is underappreciated as a hostile environment for visiting teams, because Iowa fans are not all that hostile. (Unless, it turns out, you write a column joking advocating that the Hawkeyes adopt a turnover prop).

Really, though. Kinnick is best known as the place where everyone waves to kids in a hospital. Heartwarming. Sweet. Not terrifying.

But when you’re the visiting team playing in the biggest game there in 36 years, Kinnick Stadium is a living nightmare.

Rendered incommunicado by a crazed crowd, Penn State was called for 8 false starts in the second half. 8! Just in the second half! Texas A&M and the Seattle Seahawks once engaged in some legal wrangling over the trademark to The 12th Man, but that label belonged in Iowa City on Saturday.

Buy or sell: Buy.

Every home game is a big one from here on. I suspect the Iowa crowd will continue bringing the heat as the Hawks pursue their first Big Ten title since 2004.

2. Mel Tucker & Jay Johnson

Where the heck did this come from?

And this?

Year 1 in East Lansing was a rude awakening for Mel Tucker and offensive coordinator Jay Johnson. Michigan State was 116th in scoring nationally and 108th in total offense.

Now the Spartans are suddenly explosive, though Walker is the only major addition to the roster after transferring in from Wake Forest. (And as the best running back in the Big Ten, you can’t understate how valuable an addition Walker has been.)

This dynamic duo is a major credit to Tucker’s judgement. Tucker spent his entire career on the defensive side of the ball before getting hired as Colorado’s head coach in 2019. His hire as the Buffs OC? Johnson, whom he worked with on Kirby Smart’s Georgia staff.

When Tucker was hired by Michigan State following Mark D’Antonio’s early retirement, Johnson was one of the coaches brought along from Boulder. And now we are seeing why.

Buy or sell: Buy.

Trust matters. And it can often be very difficult for offensive coordinators to earn the trust of a defensive-minded head coach. Any reservations Michigan State fans had over Johnson’s offense should be alleviated by now.

3. Kenneth Walker III, Heisman candidate

A running back winning the Heisman Trophy? In this economy?

It hasn’t happened since 2015, and when Alabama’s Derrick Henry hoisted the trophy that year, he was the first back to do so since 2009. But when the best quarterback in the country goes to Liberty, all bets are off.

Walker led the nation in rushing entering Week 6, and only enhanced his profile with 233 yards — including a school-record 94-yard touchdown.

Buy or sell: Buy.

Most years I would be selling the idea due to the bias against running backs in voting.

But with no clear-cut quarterback candidate and opportunities for Walker to perform against Top-15 opponents Michigan, Ohio State and Penn State, he might string some signature games together. It also helps that Spartans quarterback Payton Thorne is good enough to keep opposing defenses loose for Walker.

It’s an uphill climb, for sure. But if Walker ends up as Michigan State’s first Heisman finalist since Sherman Lewis in 1962, that’s still a major accomplishment.

4. Tory Taylor

Only Iowa is capable of getting everybody to talk about its punter.

Field position was a massive factor in No. 3 Iowa’s 23-20 win over No. 4 Penn State, with the Hawkeyes starting 19 yards closer to the goal line on average (their own 40 compared to Penn State starting at its own 21). Of Taylor’s 9 punts, 5 were downed inside the 10-yard line and 3 inside the 5.

Buy or sell: Buy.

This guy better have an NIL deal Monday morning.

5. CJ Stroud

That must have been a heck of a sore shoulder.

Stroud has looked brilliant since sitting out the Akron game with what was described as a shoulder injury. Last week the freshman went off for 330 yards and 5 touchdowns against Rutgers. On Saturday he threw for 406 yards and 5 touchdowns against Maryland.

And yeah, it’s Rutgers and Maryland. But it seems clear that any mental reset that took place during his week off is working.

Buy or sell: Buy.

I think Stroud is still going to have some freshman moments this year, and that could prove costly in a loaded Big Ten East. But he’s shown that he definitely deserves to be the Buckeyes’ starter, and next year is poised to be something spectacular.

6. Jim Harbaugh

Michigan is 6-0 for the first time since 2016, which is roughly the last time Harbaugh was considered the guy who would bring the program back to the top of the Big Ten.

Buy or sell: Sell.

We all know what it will take for a buy-in here: A win over Ohio State on Nov. 27.

Stock down

7. Scott Frost

Goodness gracious.

In terms of talent, it’s clear that Nebraska is the second-best team in the Big Ten West. But the Huskers have nothing to show for it with a 3-4 record that includes a 1-3 mark in the B1G.

Frost had a chance to finally pick up his signature win at home against Michigan, but Nebraska literally fumbled it away late with a chance to drive for the winning score.

Buy or sell: Hold.

Nebraska has 3 one-possession losses to Top 11 opponents … and also a loss to Illinois.

In every way but wins and losses, this is an improved product over what it has been throughout Frost’s tenure. The question is whether these closes losses are a bug or a feature. Are the Huskers about to turn the corner, or is this just how it’s going to be with Frost as a head coach?

If Nebraska finishes the season strong, I think he deserves another year to get over the hump. There are still chances for signature wins against Ohio State or Iowa. But if he can’t get either of those games, it’s time to cut bait.

8. Maryland

These Terrapins have papier-mâché shells.

After a 4-0 start, Maryland has lost two straight by a combined score of 117-31. Based on that, one can argue quite easily that the Terps had the most fraudulent September in the country.

Maryland allowed 1,026 combined yards in its back-to-back losses to Iowa and Ohio State.

Buy or sell: Sell.

The Big Ten East is too loaded for this. Maybe a much-needed off week will revitalize the Terps, but they’ll absolutely have to win against Minnesota or Indiana in their next 2 games to keep bowl hopes alive. After that, there’s not a winnable game on the schedule until the season finale against Rutgers.

9. Illinois’ offense

Wisconsin quarterback Graham Mertz passed for 100 yards against the Fighting Illini … and outgained the entire Illinois offense by 7 yards.

Buy or sell: Sell.

Chase Brown is a very good running back, as he proved in last week’s 257-yard showing against Charlotte.

However, he has nothing around him. Quarterbacks Brandon Peters and Art Sitkowski combined to go a woeful 11-of-34 for 67 yards against the Badgers. There aren’t a ton of defenses as good as Wisconsin’s, but this offense won’t be getting it done against anyone.

10. Ta’Quan Roberson

Out of the frying pan and into a 5-alarm fire.

The Penn State sophomore quarterback had only appeared in garbage time against Ball State and Villanova before being handed the reins on Saturday following Sean Clifford’s game-ending injury. And PSU was on the road against the nation’s toughest defense.

It did not go well.

Roberson was 7-of-21 for 34 yards and 2 interceptions. He had moderate success in leading Penn State to a field goal drive with his legs, but was mostly bottled up. Roberson had 27 yards on 10 carries.

Buy or sell: Hold.

You couldn’t draw up a more unfair scenario for assessing an inexperienced quarterback. I couldn’t tell how good Roberson will be in the long run, and PSU coach James Franklin might not be able to either. Surely he’ll get better with a week of game-planning to his dual threat skillset.

That said, you can bet the Nittany Lions are hoping Clifford’s injury will be a short-term one.
