It's relevant to determining the board's ability to accurately assess the likelihood of the long-term success of a Dolphins QB based on its members' "vision" alone.
I'm perfectly fine saying we can make no conclusions about him right now. What I'm not fine with is saying his future franchise QB status is a done deal, and we know that for certain based on present "eyesight" alone.
You state the facts right here clearly, vision alone is no more a representation than stats alone in determining the likely hood of Tannehill become a "great" QB. You cannot rely on one without the other in this short sample size, if you want to use stats alone on a guy like Brady, Manning or Bress who has a well established body of work so be it but in the case here you must use all available sources of data.
The eye ball test, while subjective, is just as valid as "pure data" at this point and in fact if you blend the two with objectivity you will find the likelihood of Tannehill to become a "great" QB can only be subjective at this point.
Stand on whatever side of the fence you wish but at this point you have no idea where the fence even is retaliative to all other QB measurable over a career but there has got to be consensus that Tannehill has a greater potential to become a "great" QB than a guy like Henne who is a career is a backup at best.
