In an effort to upgrade an offensive line that had its share of problems in 2009, the Chiefs struck early in free agency by signing OG Ryan Lilja and C Casey Wiegmann, who were recently cut by the Colts and Broncos, respectively. Pro Football Weekly hears both linemen have a solid chance to be Week One starters for K.C., with Lilja looking like a sure thing to start at right guard and Wiegmann likely to compete with incumbent Rudy Niswanger. It's also very possible that this won't be the end of the Chiefs' O-line maneuvering.
