With Kyler Murray back under center for the Arizona Cardinals, they were once again looking dominant as ever and the Chicago Bears had absolutely no answer for their high flying offensive attack.

Currently possessing one of the deepest and most talented rosters in the league, the Cards were back at it in Week 13.

As they look to hold the top seed in the NFC and continue to decimate the competition on a weekly basis, the Cardinals will have another big test against their NFC West rival Los Angeles Rams next week.

Now that they've put the Bears in their rearview mirror, let's discuss the two big takeaways from Arizona's authoritative victory on Sunday.

Arizona Cardinals Week 13 Takeways vs. Bears

2. The Cardinals boast the league's best offense with Kyler Murray under center 

Despite holding their own over the past few weeks with Murray out injured, there's no denying that the Cardinals are 10x better when he's at full strength and running their dynamic offense. His innate ability to move the ball around and make clutch plays through the air and on the ground are second to none.

Add to that an explosive offensive unit that features James Conner, DeAndre Hopkins, A.J. Green, Zach Ertz, Christian Kirk and Rondale Moore and the Cards are firing on all cylinders with few, if any defenses, that can stop them from lighting up the scoreboard.

With Murray back under center for the Cards, the rest of league may be in trouble once again.

1. Arizona has one of the best defensive units in the NFL 

Even though they've lost J.J. Watt for the rest of the season, the Cardinals still possess one of the most skilled and electric defenses in the NFL. Led by Chandler Jones, Budda Baker and Byron Murphy, this star-studded Cards defense still has all the intangibles to impose their will on opposing offenses and make critical stops throughout the season.

As they continue their journey towards a Super Bowl run, Arizona will look to finish out the season strong with more well-balanced performances from their defense. Plus with a highly competitive schedule still ahead of them, the Cardinals will have to bring their all on the defensive side of the ball.

With so much going for the Cardinals this year, they'll be gunning for more big wins and aiming to remain the top-seeded team in the NFC. In their relentless pursuit of a Super Bowl championship, they will be locked in and laser-focused as they continuously find ways to hail victorious for the rest of the season.

These new next few weeks will be vital to the Cards in a bid to come away with more quality wins and earn a first-round bye in this year's playoffs. So if they are to remain at the top of the conference to finish out the year, then they'll have to bring their A-game on both sides of the field until the finish line.
