Former Mississippi State QB Dak Prescott took the NFL by storm as a rookie back in 2016, leading the Dallas Cowboys to the best record in the NFC alongside fellow rookie Ezekiel Elliott.

However, with Elliott dealing with a suspension for a portion of the 2017 season, the Cowboys, and Prescott in particular, took a big step back, missing out on postseason play.

Coach Jason Garrett knows Prescott has to improve in 2018 or the Cowboys will miss out on the playoffs again. Garrett told ESPN.com that there are a lot of areas Prescott can improve in:

“He’s done a lot of good things, but he knows, we know, everybody knows he’s got to get better,” Garrett said. “One of the exciting things about him is he has such a determination to get better every day. He has a great spirit. He loves the game. He’s going to work very hard at it. I think he has to work on the physical part. The fundamentals have to continue to be refined. And that’s everybody. That’s footwork, delivery, getting away from center, his mechanics in the gun, getting the ball out quicker, being more accurate. All the things that every quarterback in this league is working on, he has to continue to refine those.

“His understanding of what defenses are trying to do to us, how the offense overlays on the defense, he’ll continue to get better at that. But this guy is a natural leader. He’s had a lot of success right away. He has a great hunger to get better. And he’s certainly going to do that.”

The Cowboys added a big-play receiver in former Jacksonville Jaguar Allen Hurns this offseason, so Prescott will have another weapon to utilize.

However, perhaps the biggest key to having success is for Elliott to be back at full speed and to play in all 16 games.
