It would be more interesting than any other move, that's for sure.
I wouldn't be shy about drafting someone with a demonstrated ability to succeed in big games. Tannehill may look the part in some respects but it's never fully translated to the scoreboard. During his final season at Texas A&M that team had a huge power rating, lots of talented players, the lead in countless games, yet finished 7-6.
Give him more time. That theory never impresses me as much as the fact that a guy wasn't playing and thriving at an early age. Projections are supposed to be cheap. Eighth pick isn't cheap.
I don't care about the tape. Big picture situational scope is more relevant, IMO. Tannehill doesn't fare well by that measure. A guy like Bridgewater does. You don't need wide receiver excuses for his career. He started immediately as a freshman and won a BCS bowl game as a big underdog against an SEC powerhouse his sophomore season. Give me that resume and I'll take my chances, above all the fretting about an individual workout.
