I wonder about the academic side of this new process, too. Are the players in the portal expected to continue to go to class and maintain their grades? I'm not sure about how this impacts their access to the football and related facilities, even though they remain on scholarship. (I could look it up, but I'm not going to before typing this out!).
And doing this midweek, while preparing for the next game and already having been in game-planning meetings and practices.... I'm sure they can see how this impacts their teammates and coaches.
I agree that sitting out for at least some period of time would make players think it through a little more, as waivers seem to be the rule rather than the exception. If not a year, then half the games, or something. I want to see things be fair for players, of course, but some responsibility has to go along with it. With coaches and contracts, it's a financial consideration. With players, there should be more balance between asking out and landing. As it stands, it seems to be overly favorable to the player, given what seems to be the waiver rate. Just find some balance, make the decision just a bit tougher due to all considerations, and be ready to tweak things as we learn from the process as we see it play out more and more.
I like the idea of the portal being open during certain times. Allowing the disruption once the season gets underway doesn't seem to be the way to work it. I'd try closing the portal starting with the first week of the season and opening it at the end of the regular season.
