I'm not going to blast you, I'm just going to say...
Accept this as fact, because it is fact: Ryan Tannehill, barring a major injury setback, is your 2018 starting quarterback for the Miami Dolphins. Period.
Like, it, dislike it, love it, or hate it, that's the score. Your head coach is all in with #17. And your head coach just put his balls on the table and showed you he has 100% job security.
A new quarterback will likely be added in the draft, to be developed in the system. This has a few benefits over trading for Andrew Luck: It will cost us less in terms of future talent, it will cost us a lot less under the salary cap, and the player WON'T HAVE A DEGENERATIVE SHOULDER ISSUE.
Some people will think this is the right course of action, some people will not. I'm just telling you what's going to happen. Hell, if it turns out that I'm wrong, ask Wildbill to ban me next fall. But I'm not wrong.
