he Oakland Raiders have an agreement in principle to acquire quarterback Matt Flynn from the Seattle Seahawksfor two draft picks -- one in the 2014 draft and a conditional pick in 2015, according to league sources. The Raiders also are trying to finalize a trade that will send Carson Palmer to the Arizona Cardinals for minimal compensation, sources said. The Seahawks signed the 27-year-old Flynn as a free agent last offseason from Green Bay before drafting Russell Wilson, who won the starting role in the preseason and led the team to a wild-card playoff win against the Washington Redskins. Flynn has made only two career starts and threw only nine passes last season. Flynn's contract has him scheduled to make $5.25 million in base salary this season. In addition to Tyler Thigpen, the Seahawks are also considering Matt Leinart as possible backup quarterbacks for next season, a source said. Palmer is scheduled to make $13 million in base salary this season and a source has said it is unlikely he would agree to restructure his contract. The 33-year-old Palmer passed for 4,018 yards with 22 touchdowns and 14 interceptions last season for the Raiders, who acquired the quarterback from the Cincinnati Bengals during the 2011 season for a 2012 first-round draft pick and a second-round selection in the 2013 draft.
