We have seen a shift in the last 10 years. It is now widely accepted that you either win a SB with an elite QB or a QB on a rookie contract. There is nothing in between that.
You simply can't pay elite money to 'above average' QBs and expect to win anything meaningful.
Our problem was/is that the front office believes Dak is elite and hence why they paid him. He isn't and so we won't win. It really is that simple. The fact that he regresses in big moments is just another nail but ultimately it was the mistake of believing he is elite that causes the issue.
Other teams are far far far smarter than us. Hence why guys like Jimmy G, Wentz etc etc all get moved on pretty quickly when they start wanting a bag and fail to deliver.
