The extra year of both eligibility and playing time (6 to play 5) was for anyone who was part of the AY2020-21 season.
Freshmen in 2020-21 would be super seniors in AY2024-25.
If they redshirt along the way they can be super seniors through 2025-26.
For future reference, the Origin Post of the AY2022-23 recruiting thread contains a blurb on this at the start of the section titled DEPARTING PLAYERS AFTER AY2022-23. (All future recruiting threads will include the info for easy reference until super seniors are no more).
