I think Harbaugh has still one year left on his contract so we are talking extension. If the Ravens are willing to trade him away I am sure he will have a say in it. And with that Miami is on the bottom of the list.
If the reports from earlier are correct and the two teams are indeed the Broncos and the Dolphins I probably would give the notch to the Broncos.
I wouldn't be surprised if a big market team like the Jets would make a jump for that.
If I am the Browns owner I would see light at the end of the tunnel and sell the house to get him. Young promising team. That'll put them right into playoff contention next year. Plus they got 11 picks in the next draft.
