Makes it a ton easier if the QB is really good.
Here's what you can't grasp. The Cowboys are paying Dak to be that level of QB. When you pay a QB what we are paying him, especially in terms of cap hits, it makes it tougher to then build a more complete roster around that QB. If you are eating up a massive chunk of cap space for the QB, you have to expect the QB to then be able to overcome some of the roster limitations caused by the fact you don't have a ton of cap space to then fill every other position with great players.
The reality here is that deep down you know what many of us are saying about Dak is accurate. But as a fan, you can't grasp the reality that we are tied to a QB who probably isn't good enough to lead us on a SB run. I get it, it's depressing and disappointing to have to come to grips with the realization that Dak and Jerry and whatever coach Jerry hires just isn't good enough to win us a SB.
