Bill O’Brien is leaving Alabama to return to the New England Patriots as the offensive coordinator, per ESPN’s Adam Schefter and Chris Low.

O’Brien has been Nick Saban’s offensive coordinator over the last 2 seasons, and he’s set to make a return to the NFL in New England. Alabama fans have been frustrated at times with O’Brien as the team’s offensive coordinator during his tenure.

This offseason, Saban has now lost both coordinators. Former defensive coordinator Pete Golding left Alabama for the same job at Ole Miss to coach alongside Lane Kiffin. Now, O’Brien is also leaving.

Saban and Bill Belichick are close friends, and O’Brien returning to the Patriots has been speculated for some time. O’Brien was the Patriots offensive coordinator during the 2011 season before leaving for the Penn State head coaching job.

For Saban, O’Brien leaving marks the 6th different offensive coordinator Alabama will have in the last 8 seasons.
