Despite the talk that a trade sending quarterback Matt Flynn from the Seahawks to the Raiders was imminent on Friday night, it still hasn’t happened as of Saturday morning. And if it doesn’t happen, the Raiders may have a Plan B in Kevin Kolb.

Adam Caplan reported that the Raiders have discussed signing Kolb, the free agent quarterback who was cut by the Cardinals this month.

The issue may be that the Raiders, who have just $2.8 million in cap space, will want Flynn to restructure his contract as part of a trade from the Seahawks. If Flynn refuses, the Raiders may try to get Kolb to sign a deal that will cost less on their salary cap in 2013 than Flynn would cost under his current contract.

The arrival of either Flynn or Kolb would lead to the departure of Carson Palmer, who now appears unlikely to play for the Raiders this season. The Raiders traded a first-round pick and a second-round pick for Palmer, who gave them a total of 24 starts, in which they went 8-16. Which doesn’t exactly instill a lot of confidence in Raiders fans about the wisdom of giving up more draft picks for Flynn.

Which may mean signing Kolb is a better move.
