GLENDALE, Ariz. (AP) — With some luck and a lot of help from his defense, Max Hall's NFL debut as a starting quarterback was a winner, against the reigning Super Bowl champions no less.

The undrafted rookie from BYU completed 17 of 27 passes for 168 yards, Jay Feely kicked three field goals and the Arizona Cardinals upset the New Orleans Saints 30-20 on Sunday.

Hall threw an interception that led to an early Saints field goal and fumbled twice, but both turned out to be key plays for Arizona (3-2). The first was returned 2 yards by Cardinals tackle Levi Brown for a touchdown. Guard Alan Faneca pounced on the other for a 10-yard gain.

Arizona's defense, awful in a 41-10 loss at San Diego a week earlier, intercepted Drew Brees three times and converted two turnovers by the Saints (3-2) into touchdowns. Kerry Rhodes returned Ladell Betts' fumble 27 yards for a score and, with 10 seconds to play, Dominique Rodgers-Cromartie returned an interception 28 yards for the game-clinching touchdown.

New Orleans' red zone problems continued. Three times the Saints drove deep into Arizona territory only to settle for field goals and a 13-10 halftime lead.

Hall took several brutal hits in the first half. He stood on the sideline as the man he had replaced, Derek Anderson, played Arizona's final series of the half.

His day didn't start out so well. Stephens-Howling returned the opening kickoff 60 yards to the New Orleans 45, but on third-and-10 Hall threw his second pass of the game toward Larry Fitzgerald, who was double-covered. Jabari Greer intercepted and returned it 26 yards to the Arizona 47. Brees completed three straight passes to set up John Carney's 31-yard field goal.

The Saints went 76 yards in 11 plays late in the first quarter. On third-and-goal from the Cardinals 1, Brees threw a play-action pass to wide-open Jeremy Shockey in the end zone to make it 10-0.
