With the way this offseason is going and based off what Pegula had claimed - seems like Whaley is doing what HE wants. Dumping and replacing both safeties (saved money and arguably upgraded), bringing back T2 for cheap, not picking up 100 former Panthers (or Jets when we had Rex), and picking up several value FA.
Rex definitely had his say in GM duties or meddling and you can tell McDermott isn't that type of guy. Just look at his staff. Its a bunch of guys with experience.
