First and foremost, I do agree that what we can say about the Senator is not enough to praise his career, including that he deserved that ring since long time ago. Having said so -and as much as I love my team and my #82 jersey- I don´t see that happening in 2018, due the complicated and huge retooling, upgrading, "win now mode" or however you wanna call the countless issues (OL, DL, LB, WR, SS, cap space, Dak Friendly Offense, Dez and etc.). Sure the Senator thinks totally positive and that is why he is more than ready for 2018, but despite that we all know that $6.95M are more than necessary, simply that money is not enough. So, in order to contribute to your point and in my humble opinion, with Witten's departure we would only aggraviate the risk of losing any other player. Just let me rephrase your sentence (I apologize for doing so, but helps to make my case): "At the end of the day, if we're talking about Jason Witten's cap hit and decreased production, why are not talkin about _____?" So yes, Witten is a sunk cost who at least will be given the honour to retire when he calls it a career, due the painful hope that father time waits him to get a ring. It hurts.
