FILE - In this May 29, 2013 file photo, Atlanta Falcons defensive coordinator Mike Nolan, right, talks with head coach Mike Smith during an NFL football practice at the team's training facility in Flowery Branch, Ga. Nolan knows his second season as Falcons defensive coordinator has been a borderline disaster. He's not sure if coach Smith and Atlanta's front office will want him back next year, but the uncertainty hasn't stopped Nolan from tinkering with his personnel and schemes to find the right formula.
