Raiders FS Michael Huff is quietly having another productive season. Huff, who had a career-high three interceptions in 2009, already has more tackles (62) than he did all of last season, he has forced three fumbles — he forced only one in his first four seasons — and he also has two sacks after making just 1½ previously in his career. His contract will expire after the season and, depending on the terms of the next Collective Bargaining Agreement, Huff could be an unrestricted free agent. CB Nnamdi Asomugha, OG Robert Gallery, TE Zach Miller and DE Richard Seymour are also set to hit free agency, so it's going to take a massive investment from the Raiders to keep all of their higher-profile free agents. With second-year veteran S Mike Mitchell waiting in the wings to become a starter, some team observers are wondering if Huff will be offered a long-term deal with a large signing bonus on the open market and move out of Oakland's price range.
