Analysis: His decision comes one day after Michael Bush signed a four-year, $14 million contract to be part of a backfield that includes disgruntled Pro Bowl running back Matt Forte. The 28-year-old Barber spent his first six NFL seasons with the Dallas Cowboys before signing with the Bears in 2011. He was a backup to Forte last season and then saw extensive duty when Forte was injured in early December.
