Tim DeRuyter? was the DC you’re thinking of I think.
To avoid raiding a teams roster after a coaching change there should be three criteria for the existing roster, minus the unenrolled recruiting class. One, only grad transfers can immediately transfer out. They’re on their very last year and should be afforded the opportunity to get to a new team for spring ball. They graduated, they earned the ticket. Second, everyone else including early enrollees should have to stay through Spring ball. Give the strength staff and new coaches a couple months to show the kids what they have. Third, after spring ball any player is now allowed to enter the spring portal, regardless of how many transfers the kids have on record. By the spring game the coaching staff should have a great idea of who’s leaving and who’s staying and can plan for the next window accordingly. It also lets the harsh emotions of the kids die down and allows them to look at their future critically. My 2c.
