Portal all dried up at defensive tackle? Is Buckeyes' roster set?

Unless something drastically changes, it does not appear as though Ohio State will add a defensive tackle via the transfer portal. As head coach Ryan Day said earlier this week, the Buckeyes have been looking, but they are not going to add a DT just for the sake of doing it. Does this basically mean Ohio State's roster is set for 2025? That is one of the subjects tackled by Jonah Booker and Dave Biddle on the Friday 5ish.
