Which means players from all teams but 4 can be in and out of the portal before most colleges either start back or they have their drop/withdraw deadline.

As for players in the 4 semifinalists, I would say their portal window closes then as well, but they are can change yet remain eligible for their current season through their last game. There may be some sour grapes, but at that point players and coaches just want to win so they should be able to be professional about it.
