Sorry about the post folks! I blame Google search results. By typing the word "secret", results from older years came up. Hence the original content here that included dates for the 2022 scrimmages.
Apparently the NCAA had proposed legislation to remove the "secret" from scrimmages held this season (2024-25). I can't find if the legislation was passed. Anyone else know?
Teams can still choose to play exhibitions or scrimmages though.
