Even though free agency hasn't started, the Raiders already might have made their biggest off-season acquisition: Rod Woodson. A Hall of Fame defensive back who suited up for Oakland in 2002 and '03, Woodson was hired away from the NFL Network to be the team's cornerbacks coach. He'll also help out with the safeties and try to keep a unit that is expected to lose its two best players afloat by imparting the guidance and wisdom he accumulated during a 17-year NFL career that saw him earn Pro Bowl nods at both cornerback and safety. CB Nnamdi Asomugha and FS Michael Huff both will hit free agency as soon as the market opens, and it would be a shock to see either one return to the team. There is depth at corner, though none of the players on the team's depth chart at the position can match Asomugha's physicality. In Huff's place, Mike Mitchell could move into the starting lineup, alongside SS Tyvon Branch. The team is high on both players, and third safety Hiram Eugene also could see the field when they opt for their "Wolverine" package, which features a third safety playing in place of a linebacker.
