There's a large group of fans on this forum that think changing the quarterback (Dak) is the magic formula that will make all this team's problems go away.
Guess they weren't paying attention between 1996-2015.
I am not certain how 'large' can be accurately applied to 'a large group of fans on the forum' in terms of solving a problem. There are a small number of very vocal fans to be sure.
I think it would be fair saying some of that group are of the same opinion as those in-and-before 2016 with Tony Romo. Some fans wanted Romo gone at all costs no matter what would later happen to the team afterwards, good or bad.
I believe the same sentiment can be accurately applied to some fans now concerning Dak Prescott's future. Perhaps some feel the team will hit rock bottom for x-number of seasons before bouncing back under another quarterback. They are willing for Jerry Jones to take that risk.
For me, that is where the 'Get Rid of Dak' concern starts. Like you inferred, Aikman's career was on its downside, then he retired, and the Mad Genius really ramped up his quarterback acquisition decision-making. Quincy Carter. Anthony Wright. Clint Stoener (sp?). Ryan Leaf. Vinny Testerverde. Chad Hutchinson. Drew Bledsoe
and Henson. Thank goodness for Sean Payton quarterback evaluation skills.
Payton is not here. I have more trust in the guys beneath Jones--even Will 'Taco Charlton' McClay--than him. He remains the final decision-maker though, with the veto power that comes with it. Who knows if his staff does a proper evaluation of a college or veteran quarterback and he nixes the process with his gut feeling--which for him is almost always gas.
Long story short, there is a magic formula in a post-Prescott era. Everyone should understand Dallas' magic formula can easily be E=mc squared with Jones' gut.
