This is the Depth Dossier: the Iowa State Cyclones, Week 9.

Iowa State just answered every question that got raised a week ago, and they did it in a 51 to 49 walk-off win over Oklahoma State.

Quarterback Jaylen Raynor got benched last week. This week he threw for 309 yards and three touchdowns, ran for another score, and finished with 581 total yards of offense. Running back Aiden Flora was just as big a factor, grinding out 221 yards and two touchdowns on 29 carries, including a 75-yard burst in the fourth quarter. This game turned into an all-out track meet, with 34 points scored in the fourth quarter alone. Oklahoma State actually took a 49 to 48 lead with 53 seconds left. Raynor answered right back, leading a 47-yard drive in under a minute, and kicker Kyle Konrardy drilled a 34-yard field goal as time expired to win it.

Dig a little deeper and this win happened two different ways at once. Iowa State ran 72 plays and averaged just over 8 yards a snap, and they held the ball for nearly 35 minutes compared to Oklahoma State's 25, which just wore the Cowboys' defense down. But then the fourth quarter turned into total chaos, and Oklahoma State actually handed Iowa State the winning field position with an unsportsmanlike conduct penalty on a touchdown celebration.

A few other things mattered here. A muffed Oklahoma State punt set up a field goal right before halftime that gave Iowa State the lead at the break. Konrardy made all three of his field goal tries and even executed and recovered his own onside kick, so the kicking game produced points, field position, and a possession in a two-point game. And freshman receiver Jamal Polite Junior had a huge night, six catches for 171 yards and a touchdown, including a leaping 43-yard grab and the catch that started the winning drive. That's big production from a receiver room that's been shuffled around by injuries all year. Raynor did throw an interception, but with everything else working, it didn't end up costing Iowa State anything.

There were no new injuries to report, so the story on the depth chart is really about roles getting settled. Raynor's big night makes it hard to imagine backup Connor Moberly taking the job away anytime soon, even though nothing's been made official. And Flora, after 29 carries and 221 yards, looks fully locked in as the lead running back now.

On the offensive line, Makai Sat has taken over as the starter, with Garret Rutledge dropping to the second string, continuing a shuffle up front that's been going on since the loss to Arizona.

The defensive line rotation keeps expanding too. Blake Hawkins is now playing about half the defensive line snaps, Jack Janikowski and Donovan Fitzmaurice have climbed up into playing about a third of the snaps, and Jace Gilbert and Max Baloun are now out there for about two-thirds of the defensive snaps. At linebacker, Beau Goodwin jumped up to playing about half the snaps, while Carson Willich and Sullivan Schlimgen saw their roles shrink, and Landon Kalsbeck, Willie Breland the third, and Montreze Smith Junior all dropped down the depth chart. In the secondary, cornerback Tyrone Cotton the third gained playing time, while Keyon Washington, Brady Hummel, and Brody Miller all lost snaps.

So Iowa State heads into next week with a shootout win, a validated starting quarterback, and a defensive rotation that's still clearly a work in progress.
