If Dak hasn't signed yet, then yes. I'm on team Dak but if im picking top 5 and he's still refusing to sign after 2 years then I gotta look after my franchise. Sorry Dak, don't be so greedy.
If Dak has signed and we hate our options and no one will trade up, I might do it anyway if I believe a QB available is a franchise kind of guy. People might refuse to trade because they believe their QB will fall... if so then I just take that QB and worst case scenario I set up a Favre to Rodgers handover situation, best case scenario I sign one QB and trade the other for a massive haul. Teams can't gamble a QB will fall if I just stash him and then declare the bidding war open.
The moral is, when you believe a franchise QB is available to you, and you don't have a franchise QB signed to a deal on your roster, then you gotta pick the rookie QB.
I say this knowing full well that most "can't miss QBs" end up sucking whereas Dak kinda figured out the game, but Dak's abilities don't matter if he refuses to sign a freaking contract. It's purely business at that point, the organization needs a QB.
