The real winners will be those perennial top ten or top 20 teams who will accept a purge of their non-contributing players so they can stock up on more “sure things.” Teams like SU will grab some kids here and there, will lose some kids here and there, and the only thing the portal will mean is an inability to keep a kid long enough to develop him.
Anyone who thinks that every change - transfer portal, NIL, conference expansion, etc. - doesn't primarily help the top teams is either not paying attention, or can’t see reality when it slaps them in the face.
