I agree. And I think that end-around to Givens would have gone to Austin if he were not in the locker-room getting fluids. That play was there to be made. Givens had the corner. He wasn't fast enough to get there. Austin would have turned that corner...and if he did, it's likely another first down run.
Washington had no answer for those outside runs. And I agree with LumberTubs, he got behind the defense and Foles badly over-threw him. Those two need to work on their deep ball chemistry.
