FLOWERY BRANCH — Matt Ryan is expanding his leadership role to include teaching young players and other newcomers in his seventh training camp with the Falcons. Tight end Tony Gonzalez has retired, receivers Julio Jones and Roddy White missed most of the offseason work and Ryan is adjusting to two new starters on his offensive line. Jones and White are back for training camp, but still Ryan is throwing to some new receivers, including Devin Hester, who was signed from the Bears.
