The Arizona Cardinals finished the 2019 season with a 5-10-1 record in Kliff Kingsbury's first season as the team's head coach. Despite the record, the Cardinals can say that the experiment to bring Kingsbury in from the college ranks was mostly a success.

Among Arizona's 10 losses, five of them were decided by one score. Therefore, the Cardinals could have been 10-5-1 and snuck into the playoffs had they won the games that they were within striking distance in.

But throughout the season, the Cardinals showed their inexperience in close games. That is something that Arizona will undoubtedly work on during the offseason leading into the 2020 season.

Of course, with a young team, the Cards had plenty of negative moments that occurred. At the same time, there were plenty of positives that should provide optimism for the fans in Arizona.

With that being said, here are the five biggest takeaways from the 2019 season for the Cardinals.

5. Chandler Jones deserves more attention

Ever since Chandler Jones was traded to the Cardinals from the New England Patriots, fewer people have paid attention to his production on the field. This season, the veteran defensive end recorded 19 sacks, 11 tackles for loss, 26 quarterback hits, and eight forced fumbles.

The 19 sacks and eight forced fumbles are career highs for Jones. But this wasn't the first season that Jones had put together a memorable season in Arizona.

From 2016-19, Jones has averaged 15 sacks, 16 tackles for loss, 24 quarterback hits, and four forced fumbles per season with the Cardinals. The 29-year-old defensive end out of Syracuse deserves more attention for being one of the most disruptive defensive players in the NFL.

4. The secondary needs some work

The most glaring issue for the Cardinals in 2019 was their secondary. To begin the season, the Cardinals had to play in six games without Patrick Peterson due to him violating the league's performance-enhancing drug policy.

But even upon his return, the secondary never displayed any sort of consistency. At the end of the season, Arizona finished with the 31st ranked pass defense in the NFL.

Furthermore, the Cardinals allowed 300 passing yards in eight of their 16 games. There's no doubt that the Cardinals need to bolster their secondary ahead of the 2020 season.

3. Kenyan Drake could be the running back of the future

Before the season began, everyone was anxious to see David Johnson revert back to being a featured back in the offense. However, due to injuries, Johnson was limited to playing in 13 games for the Cardinals in 2019.

Amid his injuries, Arizona decided to acquire Kenyan Drake from the Miami Dolphins. In his eight games with the team, Drake rushed for 643 yards and eight touchdowns on 123 carries. He also tacked on another 28 receptions for 171 yards as a receiver.

While Drake was thriving in the offense, Johnson saw his role decrease in the backfield. Even with Johnson having a lucrative contract, Drake could be the running back of the future in Kingsbury's offense.

2. Kyler Murray proved to be worth the No. 1 overall pick

From the moment that Kyler Murray declared for the NFL draft, people were questioning whether or not he could succeed in the NFL. Those questions arose from Murray's lack of size and his inexperience in college.

Nevertheless, Arizona chose to select Murray with the No. 1 overall pick in 2019. It's safe to say that the Cardinals made the right choice as Murray flashed plenty of potential in his first season in the NFL.

The rookie signal-caller finished with 3,722 yards, 20 touchdowns, and 12 interceptions in his 16 starts. The Cardinals finally found their franchise quarterback that can help the team succeed in the future.

1. Kliff Kingsbury's offense is definitely tailored for the NFL

When the Cardinals hired Kingsbury, there was skepticism that his offensive scheme wouldn't work in the NFL. The offensive-minded coach from Texas Tech proved the critics wrong in his first season at the helm in 2019.

Even with a lack of receiving threats, Kingsbury was able to make his offensive system work. In just one season under Kingsbury, the Cardinals went from having the 32nd-ranked scoring offense in 2018, to the 17th-ranked scoring offense in 2019.

As Arizona continues to build their desired roster, it's apparent that Kingsbury's offense is tailored for today's NFL. The duo of Kingsbury and Murray could become a problem in the NFC West for years to come.
