Well, I doubt very much that happens for a few reason...
1. Money:
The amount of money it will cost to get Cousins to Miami will get people fired if they don't win a Superbowl...even T-Bum is not that dumb.
2. More important positions:
The real reason Miami is clearing all money (and more to come), is because they need to sign a consistent TE, O-Guard, a Pass-Rushing DE that that can actually get to the QB, WR (If Landry leaves)...any one of those positions will be expensive if taken in FA, and though most of those positions (Including Safety, Power back, ) will be taken in the draft, one or more of those positions will need to be taken in FA for dependable quality player, of which will cost money.
3. Listening to Boomer? Really?!!:
The most obvious is biggest reason, Boomer hates the Dolphins, if he really believed this, and though it would make them better, he would be quiet, instead he he is talking about Cousins (of which he knows, never will happen), because it allows him yet again to tell people Tannehill (who will be the QB in Sept), is not a good QB, though if compared how each did in simmular Situations is as good or better then Cousins.
4. Listening to Boomer? Really?!! (part 2):
Lucky for us, Boomer is a cluesless individual that if he were serious, still would be tough to take seriously with how low his success rate is on what he thinks.
