Both cornerback Nnamdi Asomugha and punter Shane Lechler, Pro Bowlers, will be unrestricted free agents at the end of the season and the Raiders will have to franchise one of the two. For the second straight season, Oakland is likely to place the tag on Asomugha. The Raiders used the exclusive franchise tag on him this season. That guaranteed him $9.7 million and prohibited other teams from pursuing him.
