Last year many people liked Tyler Wilson of Arkansas. He had sub-9 inch hands. Didn't pan out, in fact a huge bust, waived by the Raiders despite being picked in the 4th round.
The smart thing to do is plan to develop a young QB with upside. If Murray or McCarron or Garapollo is available when we pick in say the 4th round, he may be the BPA. Despite the fact that we have more immediate pressing needs. Developing a good low cost backup QB frees up a potential cost saving in Matt Moore in a year's time. We will need the extra $5M not too far down the track to help pay for Tannehill. And who knows, Murray could have the ability to become a starting quality QB if nurtured properly by Lazor (his skill is developing QBs eg Foles). I actually think that there is a high probability that we draft a QB in the mid rounds.
