In short: Not much. In an example of divergent goals, the Atlanta Falcons started their entire third team, choosing not to risk any player in a meaningless third preseason game. Meanwhile the Jaguars, like many young teams, needed to get as many reps as possible while their new coaching staff evaluated talent. A loss is a loss, and that's never fun... but really if you're thinking this loss reflects any on Atlanta's 2012 season you need to step away from the ledge.
In terms of positive, Jacquizz Rodgers looked good, which is a definite relief. Thus far he looked a little flat this preseason, but tonight he really managed to impress in limited time as he finished with 5 carries for 24 yards and a TD. He looks ready for the season, and should fulfill his potential as a change of pace back.
One of the biggest surprises this preseason has been Dominique Davis. The rookie QB was originally seen as little more than a PS player at best, but has impressed since that time and could be the future backup for the Atlanta Falcons. While he didn't has his best outing last night, he still completed over 55% of his passes at an impressive 7.3 YPA (anything over 7 is good). Ultimately he looks like he has a future in the NFL, and when you get that from an undrafted free agent it's a good sign.
The Falcons finish preseason 1-3, but they achieved their goals. Talent evaluation of their depth was the end game, and we have a better sense for those players. Tomorrow we see the final cut, and from there the season begins in just nine days in Kansas City.
