Tim Ruskell has been pushed out as president and general manager of the Seahawks, leaving the door open for Mike Holmgren's possible return to Seattle.

Ruskell announced his resignation Thursday, weeks before his five-year contract with the team ends. He asked the team if he was going to be retained so he could begin planning for offseason moves. Owner Paul Allen, the ailing Microsoft Corp. tycoon, and Seahawks chief executive officer Tod Leiweke told Ruskell no, so he left.

"Obviously there's great sadness today but I will leave here with great memories of this place and the people. It's been the people for me," Ruskell said, his voice breaking and holding back tears during a news conference attended by his sister and the team's staff.

The team's ownership gave Ruskell full authority to shape the franchise soon after he arrived before the 2005 season. Seattle made its only Super Bowl that season.

Since then, he has presided over failed top draft choices, expensive free-agent busts _ and the awkward ouster of popular coach and former GM Mike Holmgren at the end of his contract this past January.

Ruskell brought in his own coach for 2009, Jim Mora. The 4-7 Seahawks are on their way to a second straight season without a playoff berth. Last season they finished 4-12, their worst record since 1991.

"Quite simply, we didn't win enough games," Leiweke said. "I work for a man, Mr. Paul Allen, who has exacting standards."

Ruskell understood that.

"It didn't happen quickly enough," he said, "but it wasn't because we didn't do it right."

Seahawks vice president for player personnel Ruston Webster will serve as interim general manager.

Leiweke added that he expects Mora to remain the coach, Webster would be a good GM candidate, and "stability is something we will try to push for."

No conceivable candidate knows the Seahawks better than Holmgren, who became their longest-tenured and winningest coach from 1999-2008. The first four years, he was also their GM.

Holmgren has declared his desire to return to the NFL after one year away. He took 2009 off as a promise to his wife and family but now says he wants to return to football. He hasn't specified where, or whether it is to coach or be an executive.

But the former Super Bowl-winning coach has long coveted a second chance to be a GM. He's often said how much he admires the position Bill Parcells, a good friend and another former coach, now has atop the Miami Dolphins' franchise. Holmgren still owns a home in the Seattle area.

When asked whether Holmgren is a candidate, Leiweke said, "I'm just not going to go there. I'm just not going to talk about that today."
