he was marketable — & wanted to get himself a better NIL deal — either elsewhere or by re-drawing his existing deal at BYU.
I think Fouss & Waterman felt they had too much to lose by jeopardizing their spots or roles at BYU — & potentially tainting their brand new relationship w KY. And in that, I don't blame them one bit for staying put. And maybe they both just like their stability & lives at BYU right now.
