I'm not sure that every fan understands this. The league CBA has put a really high floor on team spending. To a large degree, the amount of money that Stephen Jones pays on players is fixed. If SJ signs Dak for $50m per year or $5m per year, it has virtually no impact on SJ's checkbook. The only thing that Stephen is being greedy for in playing hardball is winning football games.
The only way an actual real Cowboys fan who also wants the Cowboys to win would disagree with Stephen is if they believe that this stance will backfire and end up costing Dallas more money. I get that and respect that.
The people who are just rooting for Dak to get the biggest possible paycheck either don't understand the rules or simply are Dak fans and not Cowboy fans.
