starting in spring ball. If they don't think Hall or Romney is clear cut better than Wilson right now then Wilson should get his job back for the remainder of the season unless he doesn't perform once he does get back to playing. Then in spring ball open it up, and open it up for real if they can possibly set aside biases and make it a true competition.
If they do that it generally becomes clear who is the best one although if they're close it could be a judgement call based on coaches just thinking the end result would be better with one particular guy over the other two.
It's a good and bad situation, it's great to have that kind of talent at that position, 3 guys that have shown they can play well and get wins, but it is bad in that unlike other positions only one guy plays QB, that's it, the other guys never see the field unless the starter gets injured no matter how good they are.
