Cole Sullivan Is Giving Oklahoma Fans Real Hope At Linebacker

Oklahoma's coaching staff is pulling out all the stops to ensure transfer linebacker Cole Sullivan becomes an integral part of their complex defensive system.

NORMAN - Oklahoma’s defense has spent spring and fall trying to speed up Cole Sullivan’s learning curve, and by all accounts the transfer linebacker has handled the load.

Kip Lewis said Tuesday that Sullivan has taken to Brent Venables’ system quickly, even with the usual challenge of mastering a playbook that has already tested plenty of newcomers in Norman.

"He's picking up everything," Kip Lewis said on Tuesday. "You could throw a kitchen sink at him, I guess he would catch it. He's been picking it up pretty easily."

Sullivan arrived at OU in winter after transferring from Michigan, where his production already made his talent obvious. The question was never whether he could play. It was whether he could absorb such a demanding defense in one offseason and pair that knowledge with his physical tools.

Lewis said Sullivan has already shown he doesn’t repeat mistakes often.

"There's not too much that he messes up on twice. He only makes one mistake. That's all he needs, and he's been responding very, very well," Lewis said.

Venables echoed that assessment on Friday, calling Sullivan a linebacker who has had a “good camp,” while also making clear he wants more from him.

“I just want to see more of it. I want to see more consistency,” Venables said.

That standard fits the way Oklahoma has approached preseason work, with the defense usually having the edge while players are pushed to meet Venables’ expectations. In Sullivan’s case, the early signs point to a player living up to what Venables and Jim Nagy hoped for when they brought him in through the portal.

"I think that's just a big factor for him being able to just pick it up pretty easily, and he's been taking it and running away with it," Lewis said.

Lewis is also set to line up alongside Sullivan and his "buddy" Owen Heinecke, giving Oklahoma what could be one of the SEC’s most talented and feared linebacker groups.

"We just love feeding off each other, playing with each other. It's just fun to have each other out there," Lewis said.

Oklahoma Rookies Gave Sooners Fans Plenty To Talk About In Week 1

Week 1 of the NFL preseason gave Oklahoma fans an early look at how a wave of former Sooners is settling into the pro game. R Mason Thomas, the Chiefs second-round pick, jumped right into the action in his debut with two assisted tackles, a quarterback hit and a pass breakup, while other Oklahoma draftees such as Gracen Halton, Febechi Nwaiwu, Robert Spears-Jennings, Kendal Daniels and Deion Burks also got their first preseason chances.

Jaren Kanak was among the Sooners whose preseason opener carried more weight than a routine August outing, and his day ended with a setback that changes the path ahead. Even beyond the draft class, Oklahomas footprint was felt with undrafted Marvin Jones Jr. seeing work for the Seahawks and Jaydn Ott getting into a Chiefs preseason game, a reminder that the Sooners pipeline into the league is already producing plenty of storylines to track.

Heath Ozaeta Gives Oklahoma O Line Stability At A Crucial Time

Oklahomas offensive line has quietly become one of the more interesting parts of its roster heading toward 2026, and a big reason is the steadiness Heath Ozaeta has provided. Entering his fourth year, Ozaeta has remained a presence for a group that now includes Michael Fasusi, Ryan Fodje and Eddy Pierre-Louis, with the Sooners also adding transfer EMarion Harris and keeping center Jake Maikkula after his strong showing last season.

Even with a reduced role in 2025, Ozaeta has stayed in the mix as a leader while younger players continue pushing for starting jobs, giving Oklahoma a level of depth it did not always have up front. For a line trying to balance continuity with a wave of new options, that matters, and it leaves the Sooners with several possible answers as they sort out how the group should look when the next season arrives.
