It does not say “different”. This is them showing off things they still could have done regardless. Best thing is that now Parsons is gone, they do not have to send Cap Waiter Boi to school to figure it all out, which is nice.
I agree with everything you just said, except everything you said is different. Just like it's been 30 years since we traded away a player for a first round pick. Different doesn't mean good. It just means different.
The Cowboys don't want to be creative with the cap. They don't want to have to sacrifice future cap money to try to create a super talented roster that can win a Superbowl. They don't want to spend more money than most NFL franchises.
Clearly they had the money set aside for Parsons. So when they didn't do that deal it was a moment of, while shit now we kind of have to spend some money. Of course they did it with no forward thinking. No thought of, we can use this money to really add some talent and push for a Superbowl. Instead they took the money and were like, let's get some other deals done.
By the way I think this has very little to do with the salary cap and way more to do with actual money. The Cowboys have like 38 mil in cap space right now. Extending these guys isn't even hurting their cap. But there is real cash going out the door and thats what hurts Jerry.
