I think this is the way this will likely play out.
Trestman and his staff are launched. All of 'em.
Emery will be brought back, but in a reduced role. I think they will hire a football guy as a team president - Director of Football Opps. Keep Emery as a scout or personnel guy etc.
This eliminates Ted Phillips from the football decision making duties and makes him the finance guy which he has done well with.
If this is the plan they come up with, expect to hear the names like Polian, Holmgren, etc. Head coaching-wise, I would be curious to see who is on their short list.
Doubt very seriously that Harbaugh is their guy. I would expect another hot assistant perhaps Bowles, etc. Either way, I am staying near the radio Monday. Hopefully they take a rebuild it attitude because this is bad.
