Under the new rule, athletes would be permitted to be contacted when they notify their current coaches, who have two days to enter the names into a database created and managed by the NCAA that will alert schools who can be recruited. The change will come with stricter tampering rules to help appease coaches who worry illegal recruiting could rise.

Currently, an athlete must ask a coach for permission to contact other schools when choosing to transfer. A school interested in recruiting a transferring player also must ask the current school for permission to recruit. Without permission from the original school, the athlete cannot get financial aid from another school, essentially blocking a transfer.
