Maybe just me, but I don't think player should be able to portal unless they aren't getting playing time.
And yes the NIL has seriously effected this, because players can now basically move at whim based on where they can get the most "NIL" *cough* booster *cough* money.
I can see D1-FBS college football basically bifurcating, as the top teams with the most "NIL" money will be able to monopolize all the best players. And it will become a death spiral for the programs that can't compete because less NIL money -> worse recruits -> poorer program performance -> less NIL money.
**** that. Although it would be amusing to see Harvard win the NCAA championship when their rich alumni base decides they want to buy one
