The net effect seems to be that the top talent will play, but the next-most talented will bounce to another playing opportunity, instead of patiently being a backup.
Therefore the top talent is spread thin at the the top. you don’t have schools backlogging studs, as they will be Portalling, looking for opportunties.
Effectively, the top talent rises to the top, filling all the available slots in a fragile level. This vastly reduces playing opportunities for the rest.
So again, I wonder how many of these second-level ‘Portalees’ will find a spot, and who will be out in the cold?
Maybe at the bottom of the pyramid the non-top tier will be the losers. (P2 > P5 > G5 > JUCO > FCS etc.)
