This is just my gut feel on the situation, I admit.
But I think Stephen loves his plan the last several years of signing cheap FAs and recent cuts to generate comp picks and focus on the draft. He thinks it's been a great success, and he's not going to change. He might even be more determined than ever to prove he's right after the failure of last year's draft class.
IOW, I think it's a bit personal for Stephen. He hasn't been running things that long. This is and always has been his baby, and he's sticking with it. Now maybe even more than ever, to prove the haters wrong.
