Rapid Reaction: Saints 40, Raiders 20

OAKLAND -- A look at the Oakland Raiders' 40-20 defeat to visiting the New Orleans Saints on Sunday night:

What it means: The Raiders bounced back well offensively after a flat performance at San Francisco last week, but their defense continued to be leaky in the third (and most important) preseason game.

Tomorrow’s talker: The Raiders’ first-team offense was solid. Quarterback Jason Campbell looked good. He completed 12 of 17 passes for 150 yards. He looks like he is improved from last year and he seems to be responding well to his coaching. If Campbell can continue to make strides, this offense has a chance to be strong. There is young, good talent here (I love rookies Denarius Moore and Taiwan Jones). The Raiders have potential to light up scoreboards.

Trending: The Oakland secondary is a concern in its post-Nnamdi Asomugha world. New Orleans quarterback Drew Brees threw at will. He had 189 yards passing before leaving late in the second quarter. New Orleans converted six of eight third-down plays when Brees was on the field. Pass defense has been a problem for Oakland all summer and it continued Sunday night. I don’t know if newly signed Lito Sheppard is the answer, but he may get the chance to show he can still play. Rookie DeMarcus Van Dyke is not ready for the regular-season lights.

What’s next: The Raiders complete their preseason Friday night at Seattle. The game will have interest because rookie quarterback Terrelle Pryor is expected to play. Oakland drafted the former Ohio State quarterback in the supplemental draft on Monday.
