As the new league year started at 1 p.m., all 17 of the Raiders unrestricted free agents hit the open market.
Most notably, that includes linebacker Philip Wheeler, defensive tackle Desmond Bryant and tight end Brandon Myers, all of whom enjoyed productive seasons on a 4-12 team in 2012.
Others free to sign with the highest bidder include starting right tackle Khalif Barnes and left guard Cooper Carlisle, defensive end Andre Carter, linebacker Omar Gaither, safety Matt Giordano, running back Mike Goodson, wide receiver Derek hagan, cornerback Joselio Hanson, punter Shane Lechler, quarterback Matt Leinart, safety Mike Mitchell, defensive tackle Richard Seymour, defensive end Matt Shaughnessy and cornerback Shawntae Spencer.
Some could still return after they test the market and compare it with what they could get in Oakland.
The Raiders have made no announcements regarding players who have been released, with middle linebacker Rolando McClain heading the list.
Given that the Raiders are already $8 million under the salary cap, players with large contracts such as quarterback Carson Palmer ($13 million salary, $15 million cap number, Tommy Kelly ($6.5 million salary, $9.4 million cap number) and wide receiver Darrius Heyward Bey ($7.7 million salary, $10.6 million cap number) can be dealt with when the Raiders need room to sign more players.
