ATLANTA -- A few San Francisco 49ers and Atlanta Falcons players are warming up in the Georgia Dome while the homegrown Zac Brown Band practices the national anthem.Trent Baalke, the 49ers' general manager, was one of the very first people arriving to the press box. The guys responsible for putting together NFL rosters become almost helpless on game days; their work is done, and all they can do is watch.I'm seated with colleagues Pat Yasinskas, John Clayton and Ashley Fox right around the 35-yard line behind the Falcons' sideline.
