Stab in the dark time
Mike McD to the Chargers as the O.C.
Mike Tomlin to the Dolphins.
Harbaugh is tough, He will bring his entire coaching staff, more than likely but his age, 66 gives me the idea a team in win now mode is the more likely destination. The talent on the Browns is astounding aside from the QB, which can be improved ( certainly not fixed ) in the off season. I'm leaning that way.
Steelers will bring in a young coach from the college ranks, they have a history of going young ( Tomlin was the youngest NFL when he was brought on. I like Notre Dame coach Freeman, personally as a fit )
The Titans will hire a mouth breather. It's what the do now. However Daboll wouldn't make me mad.
