Seems to me that when BB plays his ex staff members and associates, his teams never blow them out and in many cases they lose straight up.
In recent years and much further back, his teams have lost to Matt Patricia's Lions, Mike Vrabel's Titans, Josh Gordon's Broncos, Saban's Dolphins, and this week we have them meeting Brian Flores' Dolphins and while I don't think they will lay down or lose this game, I also don't think BB will shame them either by running up the score.
For this reason only I see Miami +19 as a live dog in week #2.
