Yes, Dallas can automatically reduce his salary to save roughly $27 million this year and spread it over 3 years and not extend Dak. He then would be a free agency as soon as the Super Bowl is played after the 2024 season.
It also means that Dallas is on the hook for those 3 dead seasons of a total of $58 million against the salary cap meaning they have to account for it before they can sign any free agents after the 2024 season or even draft. And that wouldn't be all the dead money they would have account for depending who they cut or designate as a June 1st cut this year or in the 2024 training camp.
Be careful for what we wish for. If we happen to go 12-5 again and in the playoffs again then drafting a top QB would be extremely costly in picks. Maybe Trey Lance could be the guy, maybe somebody we draft in round 6 or 7 this year could be the guy although both are crap shoots. Does anyone remember how many QBs we had after Aikman retired and before Romo (who was a pretty good QB). That would be 8. Romo had roughly 73 wins over 9 seasons and was 2-4 in the playoffs. Dak has 73 wins over 8 seasons and 2-5 in the playoffs.
Point is that we probably would suffer some Quincy Carter years again for some 6 years before sniffing the playoffs unless we completely tank a season and get the #1 pick and pick the right guy.
The question for fans is, do you want to continue winning and making the playoffs with at least a chance to win in the playoffs or do you want to jettison everything and be 5-12 for x amount of years and start thinking about the draft come November 1st every year. For me, I like winning and getting to the playoffs and having a chance. I don't want to go back to those years with knowing you have no chance at all before the season starts.
