There is a wildcard in how things shake out with the numbers. Schools still don’t have guidance from the NCAA. We don’t know for sure how players that take advantage of the extra season will count against scholarship numbers in the future. It is widely assumed that there will be no change to the numbers in the future. Let’s say Adrian Martinez decides to use his extra year in 2022. It would count against Nebraska’s scholarship total. Also, the Huskers only have eight players on the roster that are seniors.
The Huskers are determining the final scholarship numbers for the 2022 class. Plenty of factors will determine the end result. Keep something else in mind. Its easier for Nebraska to keep the number at 13 now and expand to 16. Going the other way if more players commit than the team can take is more difficult.
