My best guess:
The rumors are mixed up. Someone heard about Halvorsen, things got confused, and they conflated the rumor to include a scholarship player.
I don't think any transfer will happen but people are too quick to hammer Pewterschmidt. If a transfer happened now, it would have to be for one of two reasons:
1. the player knew he wasn't going to play or the coach desired him to leave. This could lead to Mav or Oto but they likely know the markets for their skill sets (low D-1 or D-2).
2. the player is not happy with the new coach and is good enough to choose a new school. Unfortunately this could fit Dre (but not Ausitn unless he has graduated). If he left, he would have to redshirt but would be able to land at a top 10 program for the next 3 years.
Again, before you rip me, I don't believe any transfer is coming and think the Halvorsen "transfer" has morped inot a new rumor, but Dre makes the most sense at this time.
