Not sure if free agency is the correct wording as this would insinuate players leaving for paydays. But it's most definately changed CFB. I'm not willing to discount yet, but going forward, a HS commitment & signing a letter of intent has little to know meaning. The roster management has drastically changed. It now requires recruiting High Schools, Jr Colleges, and the Transfer Portal.
I think many players are being recruited over and told if you're unhappy, play better or hit the portal. I also see & understand the purpose was to protect the player that choses to play for a HC or a OC/DC and then see these guys bail on them at the drop of a hat. We're somewhat spoiled in that area. We have sooo much stability in our coaches, but many schools just cycle them in and out.
