The New Orleans Saints and Seattle Seahawks have completed a blockbuster.

The Saints have dealt three-time Pro Bowl tight end Jimmy Graham and a fourth-round draft choice to the NFC Champions for Pro Bowl centre Max Unger and a first-round pick.

Graham, 28, is coming off of a down season by his standards, where he caught 85 passes for 889 yards and 10 touchdowns. He had a career-high 16 touchdown receptions in 2013.

Unger, 28, signed a four-year extension with the Seahawks in 2012. He was a member of their 2014 Super Bowl-winning team and played in last month's losing effort against the New England Patriots.
