There has been rampant speculation that Manny Diaz would be leaving his position as defensive coordinator at Penn State to return to the ranks as a head coach elsewhere. That speculation was a natural part of Diaz’s performance during his two seasons as defensive coordinator, as the Nittany Lions had one of the top defenses in the nation under his leadership. It appears as though he’s earned another opportunity as a head coach, as Football Scoop’s Zach Barnett is reporting that Diaz is expected to accept the head coaching job for the Duke Blue Devils.
