Cowboys dont have a "golden opportunity" to rid themselves of Zeke, there is still $11 million owed to the cap on his contract.
You cut Zeke before June 1, you eat all $11 mill on this year's cap. You do post June 1 release, you eat $5.5 this year and $5.5 next year.
That is why they are talking about Zeke taking a pay cut down to a 2 yr, $11 million deal. That is the exact same amount in dead money if you do a post June 1 release for Zeke. See, you are paying that $11 million regardless of if Zeke is on the team or not, so its not a golden opportunity to get rid of Zeke, it just depends if you want to pay that and have Zeke basically for "free" or would you rather pay that and have Zeke sit home on his couch?
Personally, I am not a fan of paying a guy $11 million to sit home, I would at least like to get something for my money and Zeke can at least be a good short yardage back.
