Now's your chance to stake your claim for after Week 1. Which one player will we all be talking about on Monday?

Mike Clay, NFL writer: Dak Prescott, QB, Cowboys. It's a big year in Dallas, as Prescott, Amari Cooper and Ezekiel Elliott all are eyeing pricey contract extensions. Prescott will get his chance to make his case that he's one of the league's best at the position with a light early-season slate that includes a home game with the Giants in Week 1. Expect Prescott to put up big numbers in a commanding victory ... even if Elliott remains out.

Dan Graziano, national NFL writer: Jimmy Garoppolo, QB, 49ers. Slow preseason notwithstanding, the Week 1 matchup against the Buccaneers is a nice, soft landing for his return from injury. It's a big year for coach Kyle Shanahan and Jimmy G in San Francisco, and I say it gets off to a quick start.

Mina Kimes, NFL writer: Jadeveon Clowney, DE, Seahawks. On Sunday, Seattle's defense faces a Bengals offensive line that's still a work in progress; don't be surprised if Clowney makes an impact from the jump, especially if Ziggy Ansah returns, as expected, on the other side of the Seahawks' front.

Jeremy Fowler, national NFL writer: Odell Beckham Jr., WR, Browns. The Browns have talked all offseason, but Beckham knows he can validate that talk with a monster debut in Cleveland. And offensive coordinator Todd Monken will design plays for Beckham and Baker Mayfield to connect early and often.

Field Yates, NFL analyst: Jacoby Brissett, QB, Colts. The opportunity for Brissett is obvious: Play well and a Colts team that has done so much right should be competing for the AFC South again. His first challenge is a good one against the Chargers in Week 1.

In Week 1 last year, the Bucs beat the Saints in a shootout. What's your top upset pick for Week 1 this season?
