Trace, you asked Roof a fair question. The obvious answer is Roof is the run game coordinator and Addison, the pass game coordinator. Roof calls the run fits and Addison the coverages. I don't understand why Roof was unforthcoming with information unless he just wants his "defensive coordinator" title to sound like more than it really is.
Gus has set the UCF defense with this format since he arrived in Orlando with Travis Williams calling the fronts and David Gibbs, the overages in 2021 and '22. Ernie Sims called the fronts and Gibbs, the coverages in '23.
TWill set the Arkansas defense up the same way:

Travis Williams | Defensive Coordinator
Marcus Woodson | Co-Defensive Coordinator
Travis Williams doesn’t want his first SEC defense to be passive or reactive. The first-year University of Arkansas defensive coordinator, known for his aggressive style in his first two years calling defenses at Central Florida in 2021-22, said he wants the Razorbacks to be the tone-setters.

Woodson spent the last three seasons as the defensive backs coach and
defensive passing game coordinator for the Seminoles.
After inheriting the nation's worst pass defense from 2022, Arkansas' new defensive coaching staff is fully prepared to take on the challenge with a hungry group of defensive backs.

Meanwhile, Bozo the clown was on Twitter trying to tell you that Addison Williams was "just a position coach."
