Weaknesses

While Illinois State had the Missouri Valley’s fourth-best scoring defense (24.9 points allowed per game) in 2024, the Redbirds struggled mightily to defend pass plays.

The Redbirds finished 10th out of 11 teams in the conference, allowing 266.3 passing yards per contest. That mark was No. 115 of 123 teams that compete at the FCS level.

Illinois State also lost a handful of its most productive defensive players — linebacker LaVoise-Deontay McCoy (graduation), defensive back Keondre Jackson (graduation), defensive lineman Jalan Gaines (graduation) and defensive lineman Steven Curtis (transferred to Minnesota) — during the offseason.

How the Redbirds matchup with OU

Illinois State isn’t a bad team by any means. The Redbirds were among the FCS’ best a year ago, and with so much returning talent, they should maintain that status in 2025.

But the season opener shouldn’t be particularly difficult for the Sooners.

Illinois State’s pass defense struggled mightily in 2024. With new offensive coordinator Ben Arbuckle and quarterback John Mateer, the Sooners’ offense will likely be very pass-heavy. The season opener will be an opportunity for that duo to show what they bring to the program.

The Redbirds’ offense is proven at the FCS level, but Oklahoma’s defense should overpower them with sheer athleticism and size. Though it will be interesting to see the defense’s performance without Danny Stutsman, Ethan Downs, Billy Bowman Jr. and Woodi Washington.

It's possible that the Redbirds can keep things close in the first half, but the Sooners' advantages across the depth chart should allow them to win comfortably and start the season 1-0.
