• After the first two practices at the Saints' facility, quarterback Matt Schaub said the Texans got to work on certain things that will help the offense.
"We got some real good work, especially in the blitz drill," he said. "It's good to go against somebody different with a different type of defense and get us ready for Saturday."
Schaub likes working against defensive coordinator Gregg Williams' scheme.
"They do a little different stuff with a little bit different scheme," Schaub said. "It's good for us, though. It's stuff throughout the year that we will see. It's good work for us to go against their group and somebody else different with a little bit different scheme so we can be prepared for all different looks."
• Receiver Andre Johnson, defensive end Mario Williams, defensive tackle Shaun Cody and outside linebacker Brian Cushing were told to rest. Kubiak doesn't like the indoor surfaces and the wear and tear on some players' knees.
• Second-year running back Arian Foster carried four times for 31 yards against Arizona. The coaches say they can see his confidence growing.
"I think, as athletes, that you always have to have confidence," Foster said. "I don't think you can be the guy without confidence."
Foster likes competing against the Super Bowl champion Saints in practice and in Saturday's second preseason game.
"They didn't say anything about that, but we know," Foster said about going against the champions. "If you want to be the best, you have to beat the best.
• Coach Gary Kubiak was asked if he had seen anybody stand out.
"I keep seeing some young guys stepping up," he said. "I watched (rookie) Garrett (Graham), our young tight end, step up and start to do some things that we think he's capable of doing."
