Cardinals' Palmer keeps preseason victory in perspective

Carson Palmer has been around long enough to know that a team's performance in its first preseason game doesn't mean a whole lot.

Especially when it comes to the first-team offense.

Palmer, in his Arizona debut, completed four of six passes for 77 yards, capping off his brief stint with a 38-yard touchdown pass to Andre Roberts in the Cardinals' 17-0 victory at Green Bay.

Palmer says his nine plays Friday night simply aren't enough to determine what the Cardinals have on offense. In fact, he says that won't be determined until Arizona finds itself in a tough game in the regular season.
