3-30-06, 8 p.m.: It looks like the long-awaited Marvin Lewis-Sam Adams reunion is about to be consummated. A NFL source said Thursday that a three-year deal for one of the league’s elite run stoppers is "imminent," as the Bengals closed in on arguably their biggest free-agent signing ever. It appears the Bengals are on the verge of completing a deal that fills their two biggest needs on defense: a physical/athletic safety and a big body in the middle. The 6-4, 340-pound Adams, who has made three of the last six Pro Bowls, is the prototypical line stuffer the Bengals have sought for years.
