There is no way a trial would occur prior to the end of the season, so I think that part is irrelevant. Barring the case being dismissed or some sort of plea deal, the season will be over well before any court resolution. Once the season is over, he no longer has to worry about being dismissed from the team, so he might be more willing to plead to a lesser charge at that point. Of course, depending on what evidence actually exists and what his story is, he may want to see it all the way the through to try to clear his name completely.
Whatever ends up happening, today's ruling is likely going to have a lot of universities revisiting their policies for the NIL era. College sports are a different world now.
