1. Palmer's debut: New quarterback Carson Palmer completed four of six passes for 77 yards with one touchdown, zero interceptions and a 149.3 passer rating. He certainly looked like the upgrade Arizona sought from its previous quarterbacks. Both incomplete passes were deeper attempts on third down. Palmer found Andre Roberts for a 38-yard touchdown against the Green Bay Packers' starting defense (Arizona was tied for last in the NFL with three passes of 38-plus yards last season). Palmer also found Larry Fitzgerald for a 21-yard gain and Michael Floyd for an 18-yard gain. When backup Drew Stanton threw a touchdown pass to Jaron Brown, the Cardinals had as many scoring passes as the 2012 team managed through two-plus preseason games. Nearly 12 minutes remained in the second quarter.
2. Mathieu and the DBs: The Cardinals are building their secondary around young defensive backs Patrick Peterson and Tyrann Mathieu. Both made impact plays in this game. Peterson, the fifth player selected in the 2011 draft, picked off Green Bay backup quarterback Graham Harrell. Mathieu, a third-round choice this year, broke up a pass with a hard hit early in the game. He later collected a 12-yard sack on a blitz from the slot. Mathieu also provided a 23-yard punt return in the fourth quarter. He and Peterson could be good together for a long time.
3. Running back picture: Rashard Mendenhall, Ryan Williams and Andre Ellington did not play. Alfonso Smith carried 10 times for 21 yards and didn't appear to have much room for running. Rookie Stepfan Taylor looked good picking up 14 yards on one of his carries. However, the Cardinals did not run the ball well in this game. They did not find out much about their running backs.
