Some things pertaining to the failure of the 2017 Green Bay Packers defense were out of coach Mike McCarthy’s control.

But the day after the Packers conclude their season with a division contest against Detroit at Ford Field, McCarthy is back in charge. What he does in January, and what expectations he sets for his players after they complete exit interviews Tuesday, are completely in his control.

Believe it or not, the Packers have the makings of a solid defense, but a couple of things have to happen.

First, McCarthy must – and most likely will – part ways with defensive coordinator Dom Capers. ESPN, citing league sources, reported late Saturday night that Capers "is not expected to return next season."

It’s possible Capers will step down or retire so both sides can part amicably and avoid the indignity of a flat-out firing.

Capers deserves that much for all the time and effort he has put into his job, all while having to endure the fickle disdain of Packers fans, some of whom over the years have called for McCarthy, offensive line coach James Campen and anyone who coaches special teams to be fired immediately.

These are the same people who want Kevin Greene to be defensive coordinator even though he only knows how to coach one position.
