”In football, during a two-year period before a prospective student-athlete's anticipated enrollment and a two-year period after the prospective student-athlete's actual enrollment, an institution shall not employ (or enter into a contract for future employment with) an individual associated with the prospective student-athlete in any athletics department noncoaching staff position or in a strength and conditioning staff position.”
NCAA Bylaw 11.4 (https://web3.ncaa.org/lsdbi/search/proposalView?id=100331)
