One report has Miami allowing Fitzpatrick to talk to other teams. That makes sense. Since his complaint seems to be the Miami scheme and his role in it, teams might be reluctant to pay up for a guy who is (1) not "team first" between the lines and in the locker room (otherwise it's still "a business" as they say) and (2) who might not like their scheme or their projected role for him.
Of course, staring down the barrel of a 3-13 or even an 0-16 season probably factors in. Playing on a bad team with lousy and unhappy players would make any player worth his salt unhappy himself, but it also does not exactly enhance prospects for that second contract.
So, the acquirer will (1) have to be willing to engage in a discussion where a player is dictating terms of play, (2) see the fit where that won't matter and (3) provide a respectable amount of compensation to Miami.
Somewhere in the discussion with the Packers the question might be posed, "if we have injuries at safety are you going to have a problem filling in there?" Jerry, on the other hand, seems willing to accumulate talent and figure it all out later. That generally doesn't work too well, but it might work in landing the player.
The attraction here is not just the player; it's how little the cap cost for a talented but currently disgruntled player. The CBA prohibits renegotiating a rookie contract, and extensions are prohibited until after the player's 3rd. season, so there's the additional advantage in knowing he cannot complain about money for two seasons. That makes the risk quite low. The main thing is you'd want to have confidence he's not the kind of personality who will blow up like Randall and pollute team chemistry if things don't go his way.
