I'm for drafting a top flight QB. However expecting a QB to come in out of college and to be the magical fix it to the rest of the Cowboys problems puts pressure on him and hinders him, especially if Garrett remains the head coach. As I said Dak can be called out when he plays bad, but that doesn't mean the other players and the coaches on the time should be let off of the hook for their bad play. Blaming the bad run game on Dak, when Dak can't control how the O line let's defenders through to Zeke for a loss of yards. The Oline getting penalties at the worst times to wipe out big plays/first downs isn't going to help out Dak and it's not going to help a young QB trying to adjust his talents to the NFL. And WRs dropping balls that hit them in the hands for sure aren't going to help out any young QB, especially one who needs those plays to happen to gain confidence in the NFL.
So, we replace Dak by drafting a QB, but the front office fails to address the other issues on the team and we are back to square one only this time there will be a bunch of threads blaming the new QB. Like Romo and Dak has been blamed, yet Garrett sticks around.
