"They are obviously an extremely talented offensive football team," Sarkisian said. "Ka'Deem Carey was the nation's leading rusher a year ago and he's a guy that we know we have our work cut out for us in trying to stop him and defend him as he obviously had a very big game against us a year ago.
"B.J. Denker is a kid who plays with everything he's got. He's a really fast kid, a great runner, competitive, throws the ball. We know their tempo is going to challenge us and the physicality of which they play with up front is going to challenge."
Each of Arizona's opponents have focused on stopping the run and it likely will not be any different with Washington.
"We need to do a really good job on our front line, our defensive line, of not allowing one to get knocked back and two not allowing these big o-linemen to get on our linebackers," Sarkisian said. "We want to be able to let our backers run and play in space.
"The second key, which may be even more important, is that we have to tackle this guy. He is a very violent runner, he does a great job of running through tackles, and we have to get a lot of hats to the football when he has the ball in his hands."
Focusing on the run does not mean that Sarkisian is not aware of Denker, but he does admit that there are difference in Arizona's passing game this season.
"B.J. is a scrappy guy," Sarkisian said. "He's going to give you all that he has and you can see that the way he plays the game. He is a really, really fast. I think they lean a little bit more on his legs than maybe they did with Matt Scott. They threw the ball a lot with Matt Scott.
"This kid's a runner and he's going to run. They pose a lot of unique challenges that way because there's Ka'Deem Carey standing next to him and when they run all the read option it is kind of pick your poison. Who do you want carrying the ball and then you have to try and tackle them."
