The Seattle Seahawks announced they'll receive a 2014 fifth-round draft choice and a 2015 conditional pick for trading Matt Flynn to the Oakland Raiders.

Seattle already has 10 choices in the 2013 draft. For trading purposes, the 2014 fifth-rounder Seattle is receiving would equate to a sixth-rounder this year. The 2015 conditional pick will presumably hinge on how well Flynn performs.

Oakland has only seven picks this year, none in the second or fifth rounds. The team wanted a quarterback without giving up picks in the 2013 draft.

Flynn becomes the third quarterback Seattle has traded since coach Pete Carroll and general manager John Schneider arrived for the 2010 season. The team previously recouped seventh-round choices for Seneca Wallace and Tarvaris Jackson.

Seattle has also acquired one quarterback by trade over that span, adding Charlie Whitehurst from San Diego in 2010 for a 2011 third-round pick and an exchange of 2010 second-rounders. The Seahawks later got a compensatory seventh-round choice for Whitehurst after the quarterback re-signed with the Chargers in free agency.

By trading Flynn, the Seahawks gain $3.25 million in salary-cap space for 2013. They also clear $8.25 million in space for 2014. That was important because the team has already allocated most of its projected cap allotment for 2014 -- about $118 million -- for other players. The team could certainly gain 2014 cap room through a variety of means, so it's not like moving Flynn was critical. But there was no way under current circumstances the team was going to carry that $8.25 million cap figure for Flynn one year from now.
