You completely missed the point and otherwise made irrelevant assertions. I bet Dak and his agent (you know one of the major parties that has to approve any deal) cares deeply about what his career earnings are.
The point is BECAUSE Dak was a 4th rounder and was paid like a 4th rounder (which is NOBODY'S "fault") while he was a starting QB on a team that went to and won in the playoffs (a simple fact), Dak Prescott (like R. Wilson prior) should NOT (and I believe will not) take nor deserves to take anything less than market value -- whatever that number is. I hardly believe that Dak is going to sit around and see Goff, for example, who has ALREADY made 50x more than he has, earn an additional 110 million guaranteed and say to himself: "nah, I am good...continue to pay me below market rate."
And Romo made a ton because of the star, so did Troy, so did Dez, so did Jaylon Smith, so did Tyron, so did J. Witten, so did Elliott, etc...and each took contracts that was near or at market rate ---many of which reset the market for their position. Why should Dak, the guy that barely has made couple of million 3 seasons plus into his career, take a penny less?
And your remarks regarding what contract/money Dak would make in Cincy is pure speculation. We will see what happens when/if say Baker Mayfield -- who pays in the same state, OH, accomplishes what Dak has...what kind of endorsement deals Baker will get.
