If Bill Belichick wants to keep Matt Patricia on his staff and in his tight circle of trust beyond this season, yeah, sure, fine, go ahead.
Slide him into the old Ernie Adams role as the unofficial director of football omnipotence. Have him help out as sort of a Matt of all trades, perhaps with an emphasis on his defensive acumen. Maybe he could even do competent work with the offensive line if that were his sole focus.
Really, it doesn’t much matter where he’s redeployed. Just get him away from a position of authority with the offense.
