1. Kevin Kolb's performance. The Cardinals' quarterback competition includes John Skelton as well, so his performance also matters. But Kolb is the most intriguing variable on the team's roster this summer. Can he command the offense and finally appear comfortable running it? Can he make it through the game healthy after injuries derailed his 2011 season? We shouldn't expect an all-world performance right out of the gates. We shouldn't read too much into a seemingly shaky one, either. Quarterbacks and offenses in general can struggle during preseason if opponents decide to crank up the pressure or get creative. But perceptions matter for Kolb or any highly paid player trying to prove his worth. In a best-case scenario, Kolb connects with Larry Fitzgerald and rookie first-round choice Michael Floyd for meaningful gains. For reference, Kolb completed 4 of 7 passes for 68 yards in his 2011 Cardinals preseason debut. Skelton completed 6-of-10 for 94 yards and a touchdown in that game.
2. Right side of the OL. The Cardinals have a new look on that side of their offensive line. Right guard Adam Snyder signed from San Francisco in free agency. Veteran Jeremy Bridges remains at right tackle for now after replacing Brandon Keith during the 2011 season. The team hopes rookie Brian Massey can grow into the starting role and take over for Bridges at some point in the near future. This game against New Orleans provides a first look. The Saints have been working with left defensive end Cameron Jordan to drop into coverage in zone-blitz packages, a change for him. We should still see Jordan, a 2011 first-round choice, get some pass-rushing reps against the right side of the Cardinals' line.
3. Cornerback competition. The Cardinals know Patrick Peterson will be starting at left corner this season. They feel great about the likelihood of him emerging as a Pro Bowl-caliber force at that position. Arizona also likes the possibilities on the other side, but it's unclear how that race will settle out. Free-agent addition William Gay represents the known. Greg Toler, coming off ACL surgery, has starting potential. So does A.J. Jefferson, who made seven starts last season after Toler was injured. Throw in third-round choice Jamell Fleming, the team's most impressive rookie during minicamps, and the Cardinals have a genuine camp competition on their hands. The assumption is that Michael Adams would project more in a nickel role, not as a starter. He's as competitive as anyone in the Cardinals' corner mix.
