I think context matters. The Cowboys were obviously looking to take a QB that 2016 draft, but were not that in love with any of them. They did not try to move up from 4th overall for Wentz or Goff. They also did not want Lynch or Cook enough to make a more substantial offer.
I think that is sometimes the best decision, but most GM’s don’t have much time to prove worthy of their job. They have a handful of years to get the team off the ground even if the previous front office left them with next to zero draft or roster assets. The QB pick gets forced too often with the high pick and chaos ensues. Just because the QB position is very important does not mean the pick should be forced-even if the team has no viable starter.
