I would definitely be exploring all options, but I still disagree with you that signing all four will prevent us from keeping or signing other players. Their contracts will be staggered, with will allow us to restructure each year to get what we need to sign who we need.
Now, that does push money down the road and eventually we'll have to either pay big or eat it, but even that will be staggered.
Let's use Tyron Smith as an example. Dallas restructured Smith in March, turning his $10 million base salary for this season into a $9 million bonus and $1 million base. That means his cap hit for this season is $6.8 million. The Cowboys did the same thing last year, which made his cap hit $5,039 million. His contract was originally over eight years, but now it is extended to 10, which is still reasonable for a player his age.
His restructure bonuses run through 2020 but they are much smaller than his base pay and all other guaranteed money will be off the books by then. So let's say the bottom falls out and Dallas needs to cut Smith in 2019. His dead cap hit would be $5.6 million and still save Dallas $7.2 million against the cap.
I'd say it's more likely, though, that instead of cutting him Dallas will continue to restructure so that his actual hit is similar to what it is this year. Now, $6 million is nothing to sneeze at and four guys making that much does mean $24 million in cap will be taken up, but considering that the cap is $155,270,000 this year and will only go up, there's plenty of space to sign other starts. Eventually you end up with dead money, but the key is to balance out that dead money with other contracts by having restructures you can rotate using.
Unless you can replace star players every four years to keep them from a second contract, that's the way of managing the cap without crippling your ability to bring in other players you need.
