It's been known for a long time that, due to a lack of available scholarships, the 2021 class is going to be very small. It's been pretty much full since summer and I can't imagine CTA going all Arizona State and reneging on players who have already committed.
Also, as far as I know, the NCAA has not yet explained how many team scholarships are going to be permitted in 2022. Will it be above 85, given the fact that everyone is getting a "do-over" for 2020? Who knows? I don't think the NCAA has said. I think they should have said that teams will have, for example, 100 for 2021, 2022, 2023 and 2024 and then the number will drop back down to 85 or whatever from then on.
I've assumed that CTA is going to be very careful to not have so many active scholarships at the end of 2021 that it severely limits his recruiting opportunities for 2022 if the NCAA doesn't adjust the numbers. I think he will proceed with caution.
I have a feeling that many schools' rosters are going to become unbalanced (in terms of numbers of seniors, juniors, and so on) because of the "do-over." I think CTA is trying hard to avoid that. But, again, 2021 was always going to be a very small class for IU because there are so few seniors.
