I'm glad you responded with an actual argument instead of the same tired lines. I still don't agree with your assertions.
If they had restructured Carr and Witten they would have gained another 10m in space. That money could have been used for Peppers or Allen and maybe we go the Championship game instead of GB.
The problem is all the half measures. If they would have just stayed with the restructures we would have 30m in cap space right now. Way more than enough to deal with any dead money. The problem in the past is that no one lived up to their contracts besides Romo, Witten,TO and Ware.
If they would have stayed the course they would be no better off than any other team in terms of usable cap space. That's the deal with restructuring. After a couple years you have added cap dollars that are you are now trying to subtract. Sure, they are currently operating at a disadvantage by taking the inflated cap charges right now but they have to be taken at some point. You can't possibly be on the cusp for 6 or 7 years. You just have to face facts and realize that at some point all the money pushing you have done has not given you any sort of advantage and if you ever want to be in a position to actually sign the 1 or 2 guys who can put you over the top, you can't be freeing up space that is occupied by previous sleight of hand every single offseason. You actually have to get that surplus which requires free up space without any previous - or minimal amounts of - restructures on the books.
Looking back on it, they probably would have been better off for 2014 if they had more talent on defense. That's indisputable, but it's also looking at the 2014 from a different perspective than anyone had in March of 2014. Hindsight is always 20/20. Had they restructured Carr last year his cap hit would be another $1M or so higher and the team would be facing a giant amount of dead money to cut him. Right now it's cap neutral to cut him. With a restructure last year it would be around $5M in the red. On the other hand, had they never restructured Carr in the first place the team would free up to $8M by cutting him right now.
Carr, Free, Spencer, Lee, Ratliff, Austin, TNew, RW31. RW11, MBIII, Gurode, Hamlin didn't earn their money
Claiborne, FJones, MJenkins, MartyB, BCarter, 2009, BCarpenter didn't live up to their draft status
And that's the nature of the business. If anyone had the ability to know whether or not a signing or drafted player would pan out they wouldn't need to restructure in the first place. They'd be so far ahead of every team that signing players to big contracts would be unnecessary. Their roster would be full of Richard Sherman or Russell Wilson type players on rookie contracts. They'd have to be the best team in the league every year because the'd be hitting home runs on every single pick and every single free agent bargain.
The bottom line is that nobody knows how things will turn out when they sign a guy or draft a guy. There's risk in every move. All teams screw the pooch at some point or another. The difference between restructuring or not is whether or not a team can take the money freed up by cutting a bad signing and use it to try and acquire a guy worth the pay. If Dallas could cut Carr right now and have at minimum $6M in cap space, would they do it? I'd have to say, "hell yes", but because they wagered on a guy producing at an older age rather than when he is in his prime, they free up nothing by cutting him unless they use a June 1st designation.
If we're going to list guys who haven't "earned their money", then we have to at least acknowledge that without signing all those contracts that turned sour the team would have the money necessary to sign guys without restructuring. Take away those missed signings and picks and what does the team have in free space or talent? Essentially, you've just stated what I have been claiming. Restructuring has been a crutch to cover for the bad decisions the team has made in the past. Seriously, take just 1/3 to 1/2 of those contracts off the books and the team probably has a cumulative $30M in space over the past 2-3 years. Turn 1/3 of those picks into just solid role players and the team is improved right now.
You can't throw good money down the drain to cover your bad spending. That's basically what restructuring every year does. You sacrifice your ability to create space to put you over the top in future years just to cover your bad decisions of recent past.
