No, this team belongs to Jerry. He will pay what he will pay. What you outline here matters to you. It doesn't matter to me. Dak is not getting paid what Mahomes got. That's not happening but if you wish to believe that, that's fine with me.
Mahomes signed an extension. That means he added years to the existing contract. He's got a 12 year deal for 477 mil with 150 guaranteed. That's what the deal is. That averages out to 39.75 AAV. If you think Dak can get that deal, that's fine. I don't care one way or the other because I know he isn't getting that deal without a championship and a long term contract, which he does not want. But as I've said, if that is what you want to believe, that's fine.
I'm not sweating it because the truth is the truth. Time will ultimately tell. Win a championship and the entire equation changes but this business of using stats to justify pay not gonna happen IMO. If it were, Dak would not be playing on the tag now. Look how long it took Mahomes to get Baseball money. Now look how long it's taking to simply get a deal done with Prescott. That tell's you everything you need to know about this situation IMO.
