FILE - This Aug. 30, 2012 file photo shows Atlanta Falcons quarterback Matt Ryan (2) and offensive coordinator Dirk Koetter, second from left, watching the team perform drills prior to a preseason NFL football game against the Jacksonville Jaguars in Jacksonville, Fla. In their first year with the Atlanta Falcons, defensive coordinator Mike Nolan and offensive coordinator Koetter helped energize the entire roster by putting star players in position to succeed and by giving all the reserves a chance to contribute. The formula has worked thus far, but Nolan and Koetter know their entire body of work this season will be judged on how well Atlanta performs in the playoffs. (AP Photo/Phelan M. Ebenhack, File)
