They missed out on Griffin. He was the only real option at franchise QB for them. If they don't try to get Tannehill in round one whether it be via trade down or reaching at #4, it wouldn't make that much sense to take a project guy in round 2.....because if they use a round 2 or late round 1 pick on a QB they had better hit on it considering these two things:
-they are building exclusively through the draft
-they have sooooo many other needs right now
That logic I think applied to why they didn't take McCoy or Clausen in round two back in 2010 when they needed a QB just as badly. Heck, they were gonna pass on McCoy in round 3 for the same reason and take a QB in round 4 or 5 that year. They like Weeden just like they liked McCoy, but I think it's illogical for them to take a QB in round 2 at this point.
