Mike Beradino had a Question recently about Parcells. In a nutshell he hasn't seen him around the practice facility since he announced he was moving to a consulting role. He also directs us to this article:
But here's another little nugget: as we hear it, Parcells wanted to outright leave/quit/retire at the beginning of the month.

So, he took the reduced role to try and prevent this.
