A week ago, the Redskins rang up four sacks – all from down linemen in their three-man defensive front, an unusual result in a scheme that is designed to free up linebackers. In Sunday’s win over the Cardinals, the Redskins managed three more sacks – all from linebackers.

The sacks of Arizona quarterback Kevin Kolb included the first career sack by first-round draft pick Ryan Kerrigan, who had his second straight strong game. “It was cool to get that one out of the way,” Kerrigan said. Outside linebacker Brian Orakpo — who plays on the right side, opposite Kerrigan — registered his first sack of the season.

“Even though we each got one, we still could’ve had more,” Orakpo said. “Kolb was getting ride of the ball quick; it just didn’t work out. We got expectations, man. We know what we’re capable of, and we’re just going to continue to work, continue to get better.”

Inside linebacker Rocky McIntosh recorded the other sack of Kolb, a play on which Kerrigan applied significant pressure. Inside linebacker London Fletcher also put pressure on Kolb – including on a 73-yard touchdown pass to Larry Fitzgerald, when Fletcher arrived a split-second too late to disrupt the throw, but drilled Kolb anyway.

Kerrigan, the 16th pick in the 2011 draft, and Orakpo, the 13th pick in the 2009 draft, expect more days like Sunday.

“We’re just getting started, man,” Orakpo said.
