FRISCO, Texas – One of the NFL's bromides is that a player makes his biggest improvement from his rookie year to his second year.

If that proves to be true for Dak Prescott and Ezekiel Elliott, just imagine what they will do for the Dallas Cowboys in 2017.

Elliott led the NFL in rushing with 1,631 yards on 322 carries and 15 touchdowns. He caught 32 passes for 363 yards and had a touchdown.

Prescott completed 311 of 459 passes for 3,667 yards with 23 touchdown passes and four interceptions. He also ran for six touchdowns.

Both were named to the Pro Bowl. On Tuesday, they were named to the Pro Football Writers of America All-Rookie team. By the end of the month one could be the Offensive Rookie of the Year or Offensive Player of the Year or Most Valuable Player.

Where can Elliott and Prescott improve?

"In every area," coach Jason Garrett generically said.

And he is correct, but the level at which both players are starting is a lot higher than any other player.

When they arrived last spring as the fourth-overall pick in the draft (Elliott) and a fourth-round pick (Prescott), they were introduced to the playbook in an entry-level kind of way. More was added as they got more accustomed to it throughout the season, but as they look to their second year the teaching will, in a way, go from elementary school to graduate school.

Prescott said he will take an "every aspect" approach to his improvement in the offseason.

"I don't know if I can just say one thing," Prescott said. "It's kind of how I've always been is just get better in the complete game of football, complete quarterback position. Take stuff from other guys that have done well in this league, regardless of position and what they do in the offseason. This is my, I guess you could say, first true full offseason. Looking forward to it and looking forward to getting better."

The breakdowns with the assistant coaches will take place in due time. For now it is about taking a breath after the season and getting ready for next week's Pro Bowl in Orlando, Florida. At some point, Prescott will sit down with quarterbacks coach Wade Wilson and Elliott will sit down with running backs coach Gary Brown and go over every play from their rookie seasons.

"You'll look at specific runs and courses and decisions that the runner made, and how we protected and how we ran routes," Garrett said. "You'll find all things in each of those areas that each of those guys can improve upon. And the same thing with Dak. You have to build on the good stuff, you have to recognize the good stuff -- and then you have to address the other stuff."

Elliott starred as a rookie despite missing most of training camp with a hamstring injury. He played 14 snaps in the preseason and had seven carries for 48 yards in the one game he played. As a result, it took him a little longer than some wanted to get accustomed to the scheme.

In Games 3-6, he had at least 134 yards rushing and never had fewer than 80 yards in a game the rest of the season. Oh, and in that 12-carry, 80-yard effort against the Detroit Lions, he was held out of the fourth quarter. He did not play in the season finale either.

"Pro football is a team sport," Garrett said. "Everybody contributes to it, and so sometimes when you're the ball carrier, you say it's all about you -- good, bad or indifferent. But it's always about us. It's always about everybody. I thought Zeke did some good things in the first game. I thought he did some good things in the second game. He put the ball on the ground a little bit -- that was on him. But we never had any doubt about the kind of football player that young man is. You talk about competitors. He's one of the great natural competitors I've ever been around."

What excites Garrett most is that Prescott and Elliott are football guys. That's what drew them to Prescott last January at the Senior Bowl. That's what they learned about Elliott in the draft process and from his coaches at Ohio State.

They won't have to be brought back to The Star kicking and screaming before the offseason program begins.

"You hate to go into the offseason losing," Prescott said. "Only one team gets to go in as a winner. It's going to allow the chip on our shoulder, the chip on my shoulder, just to grow and us to just get better and improve."
