Seahawks explore Vincent Jackson deal

The Seahawks were given permission to talk to the agents for unsigned Chargers wide receiver Vincent Jackson, but those initial talks didn't do anything to resolve Jackson's current holdout.

The Chargers plan to place Jackson on the roster exemption list at midnight eastern Friday if he doesn't report. There were no indications he will show up.

If he lands on the roster exempt list, Jackson -- along with unsigned left tackle Marcus McNeill -- faces a three-game suspension once he has signed. Jackson, who is coming off his second straight 1,000-yard season, already has been suspended by the NFL for the first three games for violating the league's substance abuse policy. He pleaded guilty in February to his second DUI since 2006.

Jackson's agents, Neil Schwartz and Jonathan Feinsod, did not return messages from The AP Friday night. Neither did Chargers general manager A.J. Smith nor coach Norv Turner.

The Seahawks were just exploring the financial cost of acquiring Jackson. The wideout is asking for a five-year contract worth $50 million with $30 million guaranteed, according to sources.

After a brief conversation with Jackson's agents, Seattle chose not to discuss terms of a trade with the Chargers. They were given permission to talk to the agents, a source said, without any trade considerations initially attached.

But at 6-feet-5 Jackson has the size that Seahawks coach Pete Carroll covets in his receivers.

Size at the position is the reason why former USC star and top-10 NFL pick Mike Williams, who is also 6-5, is returning to the NFL with the Seahawks and his old college coach this season after two years out of the league.

The 27-year-old Jackson is upset at being tendered a one-year contract as a restricted free agent, at just more than $3 million. When he didn't sign the offer by June 15, the Chargers were entitled to offer him his same salary as 2009, resulting in an amended offer of about $500,000.

If Jackson can't find a trade, he seems poised to sit out the Chargers' preseason and their first 10 games. He would then likely report for the final six games in order to accrue another season toward unrestricted free agency, per the league's collective bargaining agreement.

Seattle's interest in Jackson keeps with the promise and pattern Carroll has had since he arrived as coach and executive vice president in January: constantly seeking competition, from any avenue, to improve a team that is 9-23 in the last two seasons.

"We are going to keep competing to find out if we can upgrade the roster at all times," Carroll said Thursday. "It's the theme of the program. We are going to let it live."

The Chargers and Seahawks already have struck one trade this year. It brought backup quarterback Charlie Whitehurst to Seattle in April for draft picks.
