It's a trade for draft picks. Draft picks are NFC currency. It's cleaner and easier for trades.
Jerry will look at it this way:
-We have a mostly young roster
-We landed 2, maybe 3 first rounders last year
-We have an opportunity here and I'm 74 damn it
As I've said before...I could see the Cowboys offering up to this for a pass rusher that is good and will play at a high level for a few years...
1st round 2017
3rd round 2017
----
2nd round 2018
For a rental player...an older guy... the price would be a lot lower.
I think Stephen convinced Jerry a few years ago that the 1 player away approach was a big reason for 20 years of failure ( Joey Galloway, Roy Williams, etc.).
I think Jerry sees that each time he goes goes against Stephen's plan that it backfires.
Trade up for Claiborne - Jerry
Giving in to Dez contract demands ( Stephen was just going to keep him on the tag until he agreed to their terms).
Signing RoMc to a contract early in 2016.
Jerry followed Stephen's plan on not drafting Manziel.
Jerry followed the plan for not trading up for a QB in 2016.
Note: When I say Stephen's plan, it's really Stephen, McClay and Garrett; however, Stephen is the one that sells it to Jerry.
