FLOWERY BRANCH - It’s been a relatively busy offseason for Tony Gonzalez, and not in a physical sense. The 37-year-old Falcons tight end says he “can’t complain,” about his shape, despite being the second-oldest guy on the roster. What took up most of his time instead was negotiating a plan with Atlanta head coach Mike Smith to attend practices on a regular occasion while upholding a promise to watch his 12-year-old son, Nikko, begin his own football career this fall.
