After insisting that Percy Harvin is not for sale, the Minnesota Vikings have shifted course.

Fox Sports insider and NFL Network contributor Jay Glazer reported on Monday that the Vikings have agreed to a trade that will send Harvin to the Seattle Seahawks for a trio of draft picks. Once Harvin passes a physical, the Vikings will receive the Seahawks' first-round (No. 25 overall) and seventh-round selections in 2013, along with a mid-round pick in 2014.

It's a stunning move that will strengthen an already powerful Seahawks roster with a premier wide receiver and return threat, while simultaneously ending Harvin's often rocky four-year tenure in Minnesota. It's a bitter pill to swallow for Vikings fans. Harvin was the Vikings' most exciting player, with the ability to scorch defenses as a pass-catcher and pick up devastating chunks of yardage in open space.

Adding Harvin to Russell Wilson's arsenal in Seattle puts the NFC West -- and the entire conference -- on blast. Harvin goes from playing alongside Christian Ponder to becoming a trigger in the read-option attack Seattle rode to the playoffs one season ago.
