He will hold on for as long as he possibly can. He loves the power and attention. We will most likely see Al Davis Part 2. As long as he's breathing he will want to call the shots.
JJ has not been making substantive decisions re Cowboys personnel since probably spring of 2014 when his demand to draft Johnny Manziel was firmly vetoed by the CEO and DPP, his son Stephen Jones
Stephen's decision making of past seven years is not without criticism
But if Zeke is not suspended for six games in 2017 and Dak does not miss virtually entire 2020 they would have been a playoff club four years of past five
And lest we forget, in 2016 they lost twice to NYG by a combined four points and once in a meaningless Week17 game that otherwise *might* have been a 16-0 season
If Cowboys were to *move on* from Dak it would essentially guarantee no playoffs until at least 2024
Zeke enters 2021 just 26 yrs old so it's more than reasonable to forecast next couple seasons as serious playoff contention especially given the current condition of NFCEast
