Should the Philadelphia Eagles lose defensive right end Hugh Douglas as an unrestricted free agent, don't be surprised if they attempt to sign Green Bay pass rusher Kabeer Gbaja-Biamila to a restricted free agent offer sheet. That is the red-hot rumor, at least, around the league. A three-year veteran, "KGB" is nearly six years younger than Douglas, and at age 25 should have his best football still ahead of him. The Packers have made a qualifying offer at the middle level "tender," of $1.318 million, to retain the right of first refusal. It means that, if any team signs Gbaja-Biamila to an offer sheet, the Packers can match the contract and assume that deal. If they passed, they would receive a first-round draft choice as compensation. The Packers don't have much cap space remaining, but can hardly afford to lose their young star. Defensive end Vonnie Holliday appears poised to depart Green Bay as an unrestricted free agent and last year's big veteran acquisition, defensive end Joe Johnson, is coming off a left triceps injury that limited his 2002 season to just five games. For the Eagles, getting Gbaja-Biamila would be an upgrade over anything Philadelphia is going to be able to add with the 30th choice in the first round. Such an offer sheet scenario would pit two of the best cap managers in the league. Joe Banner of the Eagles would have to craft an offer sheet he felt would be difficult for the Packers to match. And the Packers' Andy Brandt might have to carve out a little more cap room to retain "KGB." The young defensive end, who had never even started a game until last season, has 25½ sacks over the last two years.
