Redskins heading out for practice on Thursday with a change in their defensive lineup. Reed Doughty in at SS, Chris Horton out. Horton had a critical 47-yard pass interference penalty in the loss to Detroit. Dougjhty gives the Redskins a better blitzing option and defensive coordinator Greg Blache hinted he would look to bring more pressure against winless Tampa Bay and a QB, Josh Johnson, making his first career start. Blache also said he should be one people blame for the defense's breakdowns and awful record on third downs. When it comes to throwing people under the bus, Blache said, "I should be under the bus."  Why? "Because I'm the leader." Said he would gamble more than he is normally comfortable with, too. "I've got to be a little more of a maverick," he said. Doughty, in his 4th season, missed all but three games last year and had back surgery. Surprised to be back as the starter? "You never know what's going to happen," he said. ... My take: Positive move. Redskins cannot stand still. They need to be more aggressive and that's a trait Doughty brings.
