No way you can say Jerry was going all in, when he let your #1 WR go. Especially when every DC hated trying to line up against Coop/CD/Gallup. Then they let go a starting caliber T when they knew the one on the other side is injury prone.
No they paid Dak and Zeke, and then offset costs with getting rid of guys they didn't think were playing up to their paychecks. Then tried to draft to make up for their cuts. Shrewd business moves, but not about winning it all.
Dallas is trying to keep a good team and not have down years. Good business moves, but not the all in, then drop to the bottom, then jump back to the top type plays.
