FLOWERY BRANCH, Ga. (AP) - The Atlanta Falcons have fired defensive line coach Ray Hamilton and offensive line coaches Pat Hill and Paul Dunn.

Head coach Mike Smith said Monday that his coordinators - Mike Nolan on defense, Dirk Koetter on offense and Keith Armstrong on special teams - will return next season.

The firings of Hamilton, Hill and Dunn were hardly surprising.

Atlanta's offensive and defensive lines rarely won game-long battles on the line of scrimmage. Smith said Monday afternoon that those problems contributed largely to a 4-12 season that ended with a one-point home loss to Carolina and that the Falcons need to get tougher.

Quarterback Matt Ryan was sacked a career-high 44 times. Poor play on the defensive line led to Atlanta being ranked last in third-down efficiency, 29th in scoring and 28th in total yards.
