Also, remember that entering the portal doesn't necessarily mean gone. Just means they're going into 'free agency'. Tech could still 're-sign' someone out of the portal. Schools have to constantly re-recruit their players these days. I hate it. I hope we get a better system at some point. But hate the game, not the players.
Honestly, if I had a kid in CFB these days, I'd be counseling him to consider putting his name in the portal and seeing his options. Most of these kids aren't going to have NFL careers. If they can make 6 figures somewhere as a college student, that's potentially life-changing.
