The 49ers can actually walk away from Garoppolo's contract without a massive amount of dead money on the cap. It will be worth monitoring that club, as it really would only be a QB1 away from title contention once again. I don't see Shanahan doing that for what could be a 1 or 2 year rental of Tom Brady.
I can't see the market for him to go to Nashville. I don't see the organization allowing him to fly home Sunday and not return until Tuesday each week for what is a young team because that is what he will want to go to that club.
Seeing Josh McDaniel stick with New England, I believe he will stay.
As for Dak, it will be interesting to see another club pay more than Jerry Jones will offer. If he wants to break Russel Wilson, its either stay home or go to a crappy club....but see that 49ers could walk away from Jimmy and upgrade to a younger and better arm talent with legs to keep the drive moving. That is a play I believe could happen as well.
