The Browns have asked for and received permission to interview Titans' defensive coordinator Jim Schwartz for their head coaching vacancy, a source told the Plain Dealer on Wednesday. Schwartz, a scout for the Browns from 1993 to 1995 under Bill Belichick, is believed to be intrigued by the thought of returning to Cleveland, where he began his NFL career as an unpaid intern. The Lions have also been granted permission to interview Schwartz, 42.
