Last year LSU had a transfer from Florida, Jack Pyburn, currently on Tampa Bay's training camp roster, who, along with 16 other people, was granted a temporary restraining order against the NCAA, opening the door for them to return to cfb. Apparently, the lawsuit argues the NCAA is breaching its "covenant of good faith" by denying those players the same five-year eligibility window that players before them and after them have received.
LSU would likely welcome him back, but he could also stick it out with the Bucs and take the chance that he makes the 54 man roster.
Or he might be able to enter the portal and go somewhere that is not LSU.
It's all a glorious cluster at this point. I just grab the popcorn and watch it burn.
