You wanna be frank, it is really simple, you live and die by Tannehill this season, period. There is no more excuses for Ryan, it is his third year and he needs to make a step change, sadly it isn't looking good through two games. I am a believer of stay the course however, you let him struggle and you live and die by him. If at seasons end he is marginal, you take a QB in the 2015 draft, end of story.
I'm a Tannehill supporter only because I see the bigger picture, and that picture doesn't include guys like Matt Moore, Brady Quinn, Seth Lobato or any other 2nd string garbage as the answer. If Ryan Tannehill ends up in that garbage pile so be it but I'll always strive for more instead of settling for less, which by the way is what has lead the Miami Dolphins to this juncture in time, settling for less at the QB level.
I said it when they drafted Tannehill, at least they took a shot, if you miss reload and shoot again. It isn't like you are breaking the bank for a QB in the 1st round anymore. You let Tannehill play for better or for worse, it is what it is and either way the answer is going to come in the next 14 weeks.
