Last year, Nix and Gailey passed on Tebow at 9 (then apparently tried to move up to get him), Clausen at 9 and 41, and McCoy at 9, 41, and 72. It appears that they were right to pass on Clausen, and more time is needed to tell if they were right on wanting Tebow and not wanting McCoy.
This year, it's clear that the Bills are in many ways a good situation for a developmental quarterback. They have a good, young WR corps. They have a solid QB starter who has demonstrated both his mental grasp on the game as well as his selfless, lead by example approach - who better to mentor a young, more physically gifted QB? They have a coach who clearly can bring good things out of a QB when others might not. They have an offensive line that may be one or two pieces and one or two years away from being above average, if not excellent, for years to come.
All of the above makes me really wish there was a Bradford/Stafford/Ryan in this year's draft. Unfortunately, there's not. Plenty of ink has been (metaphorically) spilled on this blog and all around the web arguing for and against the value of Newton at 3, Gabbert at 3, Locker at 34, Ponder at 34, or any other combination ad absurdum. At the end of the day there's no clear cut path when it comes to any QB prospect.
Thus, my guess is that there's no way Nix or Gailey spend a high (1-2 round) pick on a QB prospect unless they truly believe that, with a few years under Fitz/Gailey, the guy can be franchise QB material. This may be an obvious conclusion. But if it's true, what it boils down to is the title of this post: do you trust Nix/Gailey when it comes to QB evaluation?
