Free-agent defensive tackle Terrell McClain (6-2, 302) is in Atlanta today visiting with the Falcons, according to a source. McClain came to Atlanta from a visit with the Cowboys. Falcons very interested in signing McClain because he fits the system and is an up-field defensive tackle with quickness who would fit at the 3 technique. McClain also is close friends with Falcons defensive lineman Jack Crawford from their days together in Dallas. McClain could work well alongside nose tackle Grady Jarrett. McClain, 29, has played with the Redskins, Cowboys, Texans, Patriots, and Panthers.
