<h4>DE Justin Tuck/DE Mathias Kiwanuka</h4>Coming off his four-sack performance, Tuck was quick to credit Mathias Kiwanuka as the unsung hero of the Redskins game. While the sack numbers have been down this season, the defense is ninth in the NFL against the run and 13th against the pass. "The word 'sack' is a way for us to knock a guy when they don't get on the board, but he might be playing and doing a hell of a job like Justin Tuck is doing, in the run game," Perry Fewell said. "Kiwi finished the game for us against the Raiders with a sack-caused fumble and so Tuck was able to come and do that last week. I think they're going to complement each other and you'll see Kiwi come back and have a strong game, if not this game, the next game. It's important because that's what the media and that's what the fans talk about, sacks, sacks, sacks, but those guys do a hell of a job with their workload in playing the run game and that takes a lot of work, too."
