The Oklahoman newspaper listed possible candidate for the OSU job. Here is one of them:

Darrell Walker, Little Rock
An Eddie Sutton disciple of yesteryear, Walker played for Sutton at Arkansas in the early 1980s before a 10-year NBA career. Most of his coaching experience has been in the NBA as well, including head jobs with the Raptors and Wizards. He took over the program at Clark Atlanta, an HBCU, where he worked for two years before landing at Little Rock in 2018. This season, Little Rock went 20-12 and lost in the finals of the Ohio Valley Conference Tournament.

I find it hard to imagine and it won't happen. But it, at least, suggests that Darrell could move up to a higher mid-major level if he wanted to. I think he loves Little Rock and won't do that. Of course, a high major offer could be a different story.
