Dallas Cowboys quarterback Dak Prescott admits he didn't have the greatest day at the office on Sunday, but takes nothing away from an exceptional Denver Broncos' defense. The quarterback connected on 30-of-50 of his passing attempts against Denver in Week 2. The 24-year-old had 238 passing yards in a 42-17 loss suffered to the Broncos.

Prescott knew it wouldn't be easy against Denver, speaking highly of their defense before the game. The Broncos' defense, led by superstar linebacker Von Miller, is one of the best in the NFL. Even the Cowboys -- one of the top offensive teams in the league -- struggled mightily against the Broncos.

"I don't know if they necessarily took that much away from us more than it was me just not making some throws for the most part," Prescott said post-game, per ESPN. "I mean, they did a good job. They're sticky defenders. They were on us. And they made me throw in tight windows...and I just simply didn't make some of them."

Prescott has to do better

Prescott didn't back down with his comments after the game as he was his biggest critic. The Mississipi State product insisted that he must do better if he wants to give Dallas a chance to win. Prescott, who had no interceptions in Week 1 of the season, had two passes intercepted against Denver.

Overall, it was a disappointing performance by Dallas.

The Cowboys' offense struggled to find ways to score, while the Broncos' offense had it going on Sunday. Ultimately, the Cowboys paid the price by getting blown out and getting a 1-1 win/loss record.

"It's not a good feeling at all. As I said, it doesn't matter who you play, when you play the way I played tonight, you're not going to win many games in this league.

We just -- we weren't ourselves tonight."

Elliott disappoints

Dallas' superstar running back Ezekiel Elliott also hopes to bounce back in Week 3 when his Cowboys meet the Arizona Cardinals. The 22-year-old had his worst performance since he arrived in the NFL on Sunday. The running back rushed for just eight yards on nine carries against Denver.

Elliott led the league in rushing yards during his rookie season a year ago. It was a cold shower for Elliott, who led Dallas to a 19-3 win over the New York Giants in Week 1. The former Ohio State Buckeye is now ready to put in good work on the practice field.

''Never,'' claimed Elliott after the match when asked had he ever before been contained to less than 10 yards on a day. ''You just got to go to work. And go to work -- forget about it...you can't forget about it -- but you got to go back. You got to evaluate what happened. And you got to build on it.''
