RENTON - The Seattle Seahawks didn't wait until free agency began on Tuesday to make a pretty big offseason splash.

The Seahawks reportedly have agreed to a trade with the Minnesota Vikings, pending a physical, to acquire WR Percy Harvin. The trade was first reported by Jay Glazer of FoxSports.com.

According to Dan Wiederer of the Minneapolis Star Tribune, Seattle is sending three draft picks to the Vikings in return for Harvin. The Seahawks will send a first round pick and a seventh round pick to the Vikings in this year's draft and a third round pick in the 2014 draft.

It's a hefty price to pay for Harvin despite his proven play-making ability. Harvin is also going to get a new contract from Seattle with the trade. Harvin was set to enter the final year of his rookie contract this season. According to Jason La Canfora of CBSSports.com, Harvin could average more than $12 million a season under his new deal with the Seahawks.

La Canfora also reported that Seattle is now actively shopping RB Leon Washington as Harvin has been a pretty strong kick returner as well.

Harvin had caught 62 passes for 677 yards and three touchdowns in nine games before being lost for the season due to an ankle injury suffered in a loss to the Seahawks in Seattle last year.

It's the first of likely several moves Seattle will make this offseason when free agency begins Tuesday at 1 p.m. However, it's unlikely any move Seattle will make can top the magnitude of the trade for Harvin consummated on Monday.
