The Big Question: Biggest trade impact

NFC West teams have acquired 10 veteran players by trade this offseason. Which one will have the greatest impact in 2010?

Let's define impact first.

Cardinals safety Kerry Rhodes, acquired from the Jets, has the best chance to finish the 2010 season with the most snaps played among players acquired by NFC West teams. He'll start and presumably be an every-down player on defense.

Seahawks running back Leon Washington and 49ers receiver Ted Ginn Jr. have the best chance to make an electrifying play or two, perhaps swinging a game in their team's favor. Washington first must overcome a broken leg. Ginn scored two touchdowns on kickoff returns for the Dolphins last season. He had a 53-yard TD reception last season and a 40-yard scoring run in 2008.

Charlie Whitehurst, the quarterback Seattle acquired from San Diego, could make the greatest impact -- positive or negative -- based on the nature of his position. Early returns suggest Matt Hasselbeck will hold off Whitehurst for the starting job, but injuries have slowed Hasselbeck over the past two seasons. If Hasselbeck is banged up again, the Seahawks will presumably turn to Whitehurst.

A quick look at the veteran players NFC West teams have added and subtracted this offseason:

Arizona: added Rhodes; subtracted receiver Anquan Boldin.

St. Louis: added linebacker Bobby Carpenter and safety Kevin Payne; subtracted tackle Alex Barron and defensive lineman Adam Carriker.

49ers: added Ginn; subtracted quarterback Shaun Hill.

Seahawks: added Whitehurst, Washington, running back LenDale White, defensive end Chris Clemons, defensive tackle Kevin Vickerson and defensive end Robert Henderson; subtracted guard Rob Sims, defensive end Darryl Tapp and quarterback Seneca Wallace.

Seattle has been the busiest NFC West team in the trade market this offseason. I think that is because the Seahawks are the only team in the division with a new coaching staff and new general manager. They wanted to shake up the roster.
