Here are some highlights from the game:

What did we learn? The Ravens can play in a game in the Superdome without worry about the power going out. Saints fans have their priorities, because the Mercedes-Benz Superdome was half full on a school night despite attendance figures.

The key players didn't play: Starting quarterbacks Drew Brees (New Orleans) and Joe Flacco (Baltimore) did not start. Key players from both teams also were on the sidelines not playing.

Pierre Warren probably helped his cause: Warren leaped high in the air to intercept a pass from Ravens backup quarterback Tyrod Taylor in the second quarter. It was the kind of highlight play that should catch coaches attention.

Big change: The last time the Saints played in a preseason game they were penalized 22 times. The team was only penalized once in the first quarter.

The backup QB battle might be over: The Saints' Luke McCown only played in one series. Ryan Griffin played the rest of the game. Going by the "we don't want to risk any important players to injury in the last preseason game theory" this means that McCown has more immediate importance to the team than Griffin. Hence, he is the No. 2 quarterback.

The next game: NFL season opener at the Atlanta Falcons on Sept. 7 in the Georgia Dome.
