DefenseGrade vs. Falcons:CComment:Its tough to assign a passing grade when the end result was surrendering 24 points and suffering an eighth straight loss at FedEx Field. But we will this week and here are three reasons why:-- The Redskins front did a good job stuffing the Falcons ground game. The unit, led by Ryan Kerrigan, Stephen Bowen and Barry Cofield, limited running back Michael Turner to 67 yards on 18 carries (3.7 yard average). Atlantas longest run, in fact, was for 13 yards. In all, Atlantas pass-first offense amassed only 83 yards on the ground after back-to-back weeks of rushing for 121 and 119 yards.-- The unit continued to capitalize on the scoreboard, as well. Kerrigan doesnt possess the vertical leap of a NBA player, but the linebacker used timing and anticipation to jump and pick off a Matt Ryan screen pass in the second quarter. Once Kerrigan had the ball secured, he raced 28 yards for the games first touchdown and the defenses third touchdown of the season. The last time the unit scored three times in a season was 1999, when it scored four.-- Ryan completed 34 of 52 passes 345 yards and two touchdowns and tight end Tony Gonzalez hauled in 13 passes for 123 yards and a touchdown. But the Redskins battered secondary did not yield a long, backbreaking pass play (they gave had given up nine passes of 30 or more yards in the previous four games). Ryans longest completion was for 29 yards and only two others went for more than 20. Additionally, the go-ahead touchdown reception by Julio Jones in the fourth quarter required a near perfect throw and catch over Josh Wilson.Overall, the Redskins' defense held an undefeated Atlanta team a touchdown below their season average. But its no reason to celebrate. Much work remains for Jim Hasletts beleaguered unit, which still ranks dead last against the pass in yards (328.6 per game) and touchdowns (13) and struggled to get the Falcons off the field (Atlanta converted 9 of 17 third downs).
