It would be awesome but not mid - season. Can’t expect these guys to learn a new playbook now so it would just be Fitz running from the same plays. The guy knows the game, he loves it in Buffalo, he should have a job somewhere in the organization.
McD is like a Buck Showalter. He’s good enough to rebuild your culture and get you the the brink of winning, but he will just never be able to push this team over the top.
