I think that's the most likely but with recognition that...

this does seem to be the type of situation where Fisher likes to pull something out of a hat.

My guess is that the game plan, as far as passing, will be to somewhat go back to the same thing they did early on... very quick hitters, safer routes (in their opinion), taking as much 'read' out of the play as they can. So a very quick strike to a receiver wouldn't surprise me in the least... although it might scare me somewhat because I think Miami's D will be thinking the same thing.
