Former Philadelphia Eagles wide receiver DeSean Jackson has agreed with the Washington Redskins. Jackson will join Washington on a three-year deal, sources told ESPN NFL Insider Adam Schefter.

Jackson's addition seemed to be a certainty ever since he arrived in northern Virginia late Monday afternoon. He dined with Redskins coaches Monday night, went out with Redskins players Pierre Garcon and DeAngelo Hall later that night and met with team officials Tuesday.

The Redskins will pair him with a first-time head coach in Jay Gruden. But Gruden worked in Cincinnati with Marvin Lewis, who coaxed production out of players with questionable issues such as cornerback Adam Jones and running back Cedric Benson. Gruden was there with both players.

Jackson gives the Redskins a dynamic playmaker, something they have not had in some time. Jackson has averaged 17.2 yards per catch in his career. The Redskins haven't had a receiver average more than 17.0 yards per catch with at least 50 receptions since Santana Moss in 2005.

No other receiver with that many catches has even hit 15.0 per catch. Only two receivers since 2008 have averaged more yards per catch -- Vincent Jackson and Malcolm Floyd. And only Mike Wallace has as many touchdown receptions (21) of at least 30 yards as Jackson.
