Three times against Arizona, the Raiders needed a single yard, a situation that would have called for the likes of a big, short-yardage specialist.Three times the Raiders called Darren McFadden's number Friday night. And three times, McFadden was stopped for no gain.It was the prime situation for which Michael Bush was used in previous seasons and, many thought, the likes of fullbacks Marcel Reece and Owen Schmitt might be utilized now. Instead, McFadden was sent up the gut, to no avail."He's the guy we're counting on to be our bell cow and we wanted to hand him the ball and see if we can get a yard," Raiders coach Dennis Allen said of McFadden. "When you look at those plays, the result is obviously not what we're looking for, but when you actually go back and study the tape, we're a lot closer to getting it than what it might look like live and in person."Two of the stops came at the goal line in the first quarter and the Raiders had to settle for a field goal. The other came on a second-and-one situation near midfield.Still, McFadden did have explosive gains of 22 yards on a run and 17 yards on a catch and run and finished with 51 yards on 10 touches. In two preseason games, McFadden, coming off a season-ending Lisfranc sprain to his right foot, has 13 touches for 89 yards."We're a work in progressand I'm not real concerned about it," Allen said. "I know we're going to get it corrected and we'll get to where we need to get to."Allen said McFadden would play again Saturday against Detroit.
