No crap. I said his agent is going to want an extension. It will not be a simple restructure. It will take time to negotiate.
The only way the Cowboys give an extension to Clark is if they want to give him one.
He has absolutely no leverage over them as long as they decide in the next few days before his roster bonus is due.
In fact, they could easily use that as leverage. They could say, take this large restructure check or we'll trade or release you before then.
As I said in one of my earlier posts, restructures commonly add a year or two to shorter contracts because they need that to spread out the signing bonus they give the player immediately to offset this year's salary which also reduces their salary cap hit this year.
Extensions are for when they want to keep a player longer. Restructures that add a year or two with poison-pill/backloaded years designed to force a release or follow-up restructure are not an extension, but simply ghost years to spread out the signing bonus this season.
Again, I never singled out Clark. What you said was agents will demand an extension. I said the Cowboys don't have to do that and they don't.
The Cowboys will focus on restructures and if they give an extension (and you'll know it's an extension if the last year or two doesn't contain a super high salary as sometimes it's the year before last year of contract).
My guess is with Clark they will restructure him and while doing it, they may add 1-2 years to his contract that he will never play with the Cowboys without a follow-up restructure.
That said, his contract is actually team friendly enough to just restructure without adding any years unlike most players.
His contract is a rare situation that greatly benefits the Cowboys salary cap wise because there's no penalty (dead money) for trading/releasing him, so it's entirely up to them what to do with him.
