I think (hope) you,
@Da Boyz Mom , and I can agree on the following:
1. In sports where redshirting is not the norm, the reduced roster turnover under new rule will decrease HS (or portal) signings. (i.e., if a true senior who graduated in 2024 got to play in 2025, it would have displaced a HS signing, assuming that's who got his "spot").
2. Under the new rule that disallows redshirting, incoming freshmen will be increasingly expected to contribute, where before, they were likely going to be redshirted. Therefore, coaches will likely increasingly look to the portal to fill open roster spots rather than HS seniors who would immediately be on the clock in the fall.
