Here me out Phins fans.
Joe Philbin actually knows what he is doing.
I've seen a great deal of consternation about how Philbin is handling this team, and how he is bizarrely acting around Tannehill's status as the starter on Sunday.
I can provide a brief amount of context into Philbin's history with the Packers, and why I think this is the exact kind of thing Philbin does, and why it should help the Dolphins improve.
Philbin is not an X's an O's coach. He is not a playcaller. His a facilitative coach who prepares teams for games. In Green Bay, Philbin did not call offensive plays. He did not teach players. He prepared game plans with Mike McCarthy, and he led the offense in building them into a team. Philbin is a motivator, often by uniting the team against an antagonist. In Green Bay, it was often by spinning the offense against the defense, or by using "bulletin board material" in divisional games. The Packers lost to the Giants after their 15-1 season, largely because Philbin's son had tragically died right before the week of the game. Philbin was gone and the team had lost their main motivator, who himself was grieving. The entire team lost its poise because the non-play calling OC lost his son. That's how important Philbin was to Green Bay. (That and the Giants played great).
Do you know who he is using as the antagonist right now? The Miami Dolphins, represented by himself.
This is a team of players who has let Ryan Tannehill down. Sure he isn't the best QB in the league, but play for play, he is suffering from more duress, more WR drops, and more blown protections than any other QB in the league. The team has not put forth the effort to have Tannehill's back.
They will now.
For whatever reason, the players on the Dolphins have not yet performed the way that Philbin expects them to. Thus, he is left with the difficult position of having to get his team to unite against a common enemy, when the team has shown an inherent inability to do so when facing an actual opponent like the Bills or the Chiefs.
Will this plan work? I honestly doubt it. It worked in Green Bay, but here you had Aaron Rodgers and an incredibly well-knit team on the defensive side. I am not sure if the Dolphins have the players with the mental toughness that the Packers had under Philbin. Will they wither under the pressure and unite? Or will they crumble? Maybe this tactic is unwise for a team like the Dolphins, who showed that they will not rise to the occasion when challenged (see all of 2013).
TL;DR: Philbin is trying to get the rest of the team to stand up for their quarterback through their performance on Sunday. Tannehill isn't the problem and Philbin knows it.
UPDATE EDIT - So this /r/nfl thread and link just confirms what I'm thinking. Philbin is intentionally letting himself be the bad guy for awhile with the team to motivate them to back Tannehill (which is exactly what they did).

Predictably, the comments don't really seem to get the nuance of this, although Lobo_Marino has a great comment in there. I expect the Dolphins to come out and just crush the Raiders.
