Oh no, I get why the Cowboys want more years because it makes their cap management a lot easier. I get that. But that sounds like a Dallas problem and not a Dak problem. Just like when Dak was the 77th highest paid QB in the NFL over the last 4 years...that was a Dak problem and not a Cowboys one. I don't remember the Cowboys going to Dak and saying, "man Dak, it is such a shame that you are being paid less in 4 years than Matt Stafford makes in 1 half of football...here let me help you out."
Dallas had 4 years to plan for Dak's new contract...plan accordingly...it is not incumbent on Dak to help managed Dallas' cap...ESPECIALLY not on his second (first real) contract.
And yes, if Dallas wants to TRULY treat Dak like Wentz and Goff, they owe him $26MM. So if Dallas wants Dak's contract to end in 2024 like Wentz and Goff...they can start by paying him an extra $26MM so that at the end of their second deals...Dak would have made about the same as them.
Simple.
