Pretty sure all scholarships are year to year anyway. Most schools just honored them because no one would come if you just kicked everyone off the team every year. Now it's all different you get recruited over etc, but theres no rule they have to take you off or bring you back etc.
The P5 all guarantee your scholarship for four years, even if you quit the team.
The PAC12 was the first conference to do this but now they’re dead.
