Patriots bring back Bill O'Brien in dual role

Bill Belichick welcomed Bill O'Brien back to the New England Patriots on Thursday in a reunion geared toward getting the most out of quarterback Mac Jones.

O'Brien, who spent the past two seasons as offensive coordinator and quarterbacks coach at Alabama, will have the same dual role with the Patriots. O'Brien knows those roles and expectations well under Belichick, who first hired him as an offensive assistant in 2007.
