I believe the B1G conference put that 4 year clause into NLIs in 2014. Not all programs or conferences have the same. That written, one further caution. The money can be guaranteed for 4 years, but the coach can still cut a player. That's happened before at some programs in and beyond the B1G. For example, lots of kids transfer out of Maryland after first year. Tillman constructively exits kids by telling them they are out of the picture and he'll give them a release if they'd like to play somewhere else. That's no different from being cut.
