BALTIMORE — If the goal in preseason games was solely to win, the Baltimore Ravens would have been delighted. The main objective is to get ready for the regular season, and that's why the Atlanta Falcons almost certainly derived far more satisfaction from Thursday night's preseason game — even though the Ravens pulled out a 27-23 victory. Matt Ryan threw for 97 yards and a touchdown in four series, and the Falcons bottled up Baltimore's starting offense in the first half before the Ravens' backups rallied with a 20-point fourth quarter.
