In the wake of his team's fourth straight loss and its 13th in 14 games, Washington Redskins coach Jay Gruden addressed a host of problems during his Monday news conference, including potential lineup changes and the need for vast improvement in third-down efficiency and the running game. Gruden did not specify which players or positions might be in flux but said he does not intend to replace starting quarterback Kirk Cousins with third-stringer Colt McCoy. In Sunday's 30-20 loss to the Arizona Cardinals, the Redskins' ninth defeat in a row on the road, Cousins threw three interceptions in the fourth quarter. Cardinals safety Rashad Johnson returned the third interception 28 yards for a clinching touchdown with 18 seconds to play. The game was an otherwise statistically productive performance from Cousins, who had 354 passing yards and two touchdowns. "We'll see if there's a way we can upgrade our roster," Gruden said. "Mainly I'm looking at maybe ways to prepare, practice, our practice schedule."
