NEW ORLEANS, Louisiana (AP) - Thursday night's final preseason game for the Baltimore Ravens and New Orleans Saints (on ABC7 at 8 p.m.) has the potential to serve as a bit of a dry run for Baltimore, which will revisit the Superdome during the regular season for a Monday night game on Nov. 24.

However, Ravens coach John Harbaugh said most of his regulars would not play. Superdome noise levels in the preseason are unlikely to approach those of a regular season night game anyway.

Still, there are a few potential regulars of which Harbaugh wants to see more. Namely, rookie safety Terrence Brooks, the club's third-round draft choice.

"Terrence has really made a move in the last week or so. He's playing faster; he's playing more assured of what his assignments are," Harbaugh said. "We'll see a lot Thursday night from Terrence. If he flies around, does the right thing and plays fast ... it'll be a real good sign for us."

Harbaugh and Saints coach Sean Payton also insisted that the result on the scoreboard is important to them - even if they won't be playing a lot of starters - because even preseason victories speak to the winning culture they're trying to promote in their organizations.

Both clubs have won their first three exhibition games this summer.

"How you play in the preseason matters," Harbaugh said. "Somebody can call B.S. on that and say that's not right, but I think it matters. ... If we're a good football team, we should play well every time we go out there.

If the Saints win, they'll go unbeaten in a preseason for the first time in club history.

"Something that Sean really believes in is competing in everything that we do," Saints defensive tackle Akiem Hicks said. "Whether or not some teams don't take it as seriously as others, it's something we take seriously."
