It is not the public aspect, nearly as much it has been become acceptable or seen as being a good corporate citizen to do. This will bring even more money into the sport.
The question becomes do more players take money over playing time. This applies to both directions of the portal. Does the 3rd string lineman at UT leave $50k for potential playing time at a G5? Does a starting and impactful G5 player leave for NIL money and more exposure, but potentially less playing time?
I personally think the truly competitive-minded players will always choose playing time. It makes identifying the right people for your program even more important. There will be plenty of money 'thrown at problems', but just like real world business, that strategy rarely works.
