I seriously question if anyone will spend a first round pick on him given the situation. Given the gravity of what has taken place, at least "some" jail time seems almost certain.
It's only two months until the draft and I just don't see much movement on the case in that time. Third round or higher picks are like gold to NFL teams-especially the good ones who draft well.
If he drops out of the first and second, his agent would be best asking teams NOT to draft him in the later rounds. That way, when the smoke has cleared a bit, be can pick and choose his situation-hopefully he is wise enough to pick and organization that does not suffer fools.
The downside being an UDFA contract is only for two years (I think?) So if he turns out to be a bust then he's screwed.
Upside being, if he cleans up his act and produces on the field he gets a big payday sooner.
