The NCAA give you 34 days (from the day you start Spring Football) to fit in 15 practices. 12 of which you're allowed to have physical practice, but you can't have more than 8 tackling practices. Plus, I believe you can't have two tackling practices in a row.
Therefore Snyder is compressing practice into a narrow window when it wasn't necessary. 25 days (9 days under the time allowed)
RULE
A college is allowed to hold 15 spring practices, including a spring game. Schools are also permitted to have separate days during which activities are limited to required conditioning activities and/or watching film. These 15 practices must be completed within a period of 34 consecutive calendar days. Only 12 spring practices may permit physical contact, none earlier than the third practice session. Tackling is allowed in eight of the twelve contact sessions. Up to three of the eight tackling sessions may be devoted to 11-on-11 scrimmages. The optional spring game counts as one of the three scrimmage days.
