Rapid Reaction: Arizona Cardinals

GLENDALE, Ariz. -- A few thoughts on the Arizona Cardinals' 40-11 win over the Indianapolis Colts.

What it means: Not only are the Cardinals winning games this season, but they're winning games they're supposed to win. That hasn't happened in Arizona in a while. The worst-kept secret in the NFL is how the Colts struggle in the first half. After Arizona scored on its first possession Sunday, it just kept piling on, but it wasn't just the offense that carved apart the Colts. The Cards' defense kept Indy under 100 yards for three quarters, and the Colts' first touchdown was on a broken play with a great catch. But Arizona isn't playing like a team waiting to lose like it was last season. This is a legitimate contender this season, and if it wasn't for a new offense that took almost half the season to get going, we would've been talking about the Cardinals for weeks now.

Stock watch: Rashard Mendenhall might not have ran for the most yards of the season, but there was something different about him Sunday. He had an extra pep in his step, or a set of afterburners on his heels. The veteran running back bounced outside throughout the first half instead of his typical inside-the-tackles bulldozing. He burned some rubber on his few plays, including a 13-yard run in the first half on which he hit the corner and shot up the sideline. Mendenhall looked more like rookie running back Andre Ellington than his usual self, but if Mendenhall can produce burst plays, Arizona's options at running back just got deeper.

Hitting their goals: The Cardinals hit most of their offensive goals Sunday. Their 40 points exceeded their time of possession (36:49) and Arizona converted 50 percent of their third downs, another area of focus for the Cards.

Floyd keeps it up: Michael Floyd set a career high last weekend with 193 yards, but he didn't let up Sunday. His 104 yards were his second-highest total of the season and the first time he went over the 100-yard mark in back-to-back games in his career. But it wasn't just the quantity of yards, it was the quality. Normally facing single coverage, Floyd's catches were mostly highlight-worthy and made against the sideline. He's able to benefit from the attention Larry Fitzgerald gets, but he's still making great catches.

What's next: The Cardinals face the Philadelphia Eagles on Sunday at Lincoln Financial Field.
