The Facts: When he was asked Monday how one teammate, CB Chris Culliver, challenged him in practice, Jackson made one point clear. "I don't think no one can guard me," Jackson said. "It's how I feel about myself. I don't feel no one can stop me. You can get Darrelle Revis, Richard Sherman -- whoever you want to get."

Diehards Line: As ESPN.com's John Keim reminded readers, defenses certainly had a tough time stopping Jackson from going deep last season. He led the NFL with 13 catches for 40 yards or more -- five more than any other wideout. He also averaged an NFL-best 20.88 yards per catch -- nearly three yards more than the next receiver, Arizona's Michael Floyd. There's more: Since entering the NFL as a second-round pick in 2008 with Philadelphia, Jackson has averaged an NFL-best 17.68 yards per catch. Also during this time, Jackson has 48 catches for 40 yards or more -- 11 more than anyone else. Last season, the Redskins wanted their quarterbacks to take even more deep shots with Jackson than they did. They were told to throw to him even if he was covered, knowing one of Jackson's strengths was separating from defensive backs downfield. It's a learning process, one that's on-going with his QBs, including starter Robert Griffin III, who connected with him on five plays for at least 40 yards. This season, the Redskins want to focus heavily on the run and use more play-action. It could make Jackson even tougher to guard.
