The Packers have signed T.J. Lang, a fourth-round draft choice out of Eastern Michigan. Lang, a guard/tackle, started every game in his final three seasons in college. "I think Lang has really made some big steps since he's been here ..." Packers coach Mike McCarthy said after a June practice. "Athletically, there's days I thought he was a tackle, there's days I think he's a guard. So that tells you about where his flexibility is physically. "Very happy with him."
