The Atlanta Falcons, who've been pretty much silent since the start of free agency, now are making a wee bit of noise.
Davis' return could be bigger than it seems on the surface. He's been a decent backup, but he could have a chance to challenge Jamaal Anderson, who has been disappointing in his first two seasons, for the starting spot. With Davis' return, free-agent defensive end Mike Montgomery has canceled a visit to Atlanta.
With lots of room for outside linebacker help after the departures of Keith Brooking and Michael Boley through free agency, Peterson doesn't fit that profile. He's been a middle linebacker, but the Falcons may view him as a backup for Curtis Lofton. Peterson played for coach Mike Smith when he was defensive coordinator in Jacksonville.
