Memphis Pre-Seaon All American Sitting out Season

Thought this worth a standalone thread.
Kenny Gainwell was 1st Team All AAC last year gaining >2,000 all purpose yards and a pre-season All American running back this year. Previews of upcoming season raved about his talent.
Is there a Transfer Portal in his future? Mike Williams is in a 2 year MBA program so it makes sense to sit out, but Gainwell is NFL-level talent and he would be just a red shirt sophomore this season. Why delay your NFL check another year, unless you believe a P5 school would help your prospects? I don't see him spending another 4 years in college.
