Former Giants running back Tiki Barber says he battled depression following his retirement from the NFL. Barber has spent the past four months working out in an attempt to make a comeback, although his chances rest on the league and its players reaching a new collective bargaining agreement. "The game never needs you because there's always someone else to come and take your place," he said. "But right now, I need the game." Barber's life took a downward spiral shortly after his retirement. What started as a promising career as an NBC football analyst ended in his firing and his marriage to his college sweetheart collapsed.
