Eight big questions going into NFL Week 1

With all 32 NFL teams starting with a clean slate, Week 1 is full of mysteries.

The prevailing trends of last season have given way to fresh opportunities. And while some players and teams might find themselves in similar positions as the ones they faced last season, an offseason full of changes could produce a sea change for several others.

Here are eight questions for Week 1:

1. Will Khalil Mack attack the Packers?

The Bears are understandably excited to put their new defensive star to work against their rival after engineering a trade Saturday and giving him a six-year, $141 million extension. Firstyear coach Matt Nagy, however, said Chicago will be “smart” in using Mack as the pass rusher learns a new scheme.

For the Bears to beat the Packers for the third time since 2011, generating pressure on Aaron Rodgers will be key. The two-time MVP has a 15-4 record against Chicago with a 42-9 touchdownto-interception ratio.

2. Are the Steelers running out of time with Le’Veon Bell?

The clock is ticking for Pittsburgh and its all-pro running back, who has yet to report or sign his one-year franchise tender.

Even if he makes his way back in a timely fashion, it remains unclear how quickly he can get into top form.

After reporting to the team the Friday before Labor Day last year, Bell logged a career-low 47 total yards in the opener vs. Cleveland.

3. Can Nick Foles break the Eagles offense out of a preseason funk?

With Carson Wentz still recovering from December’s knee injury, the Super Bowl MVP is back in the saddle as the substitute starter for the defending champs. But there’s considerable question about whether he can extend the magic of last postseason, as the offense was off-kilter throughout the exhibition slate.

Coach Doug Pederson might look to replicate the game plan he used for Foles in the divisional playoff win over the Falcons, when the quarterback had 20 of his 23 completions (on 30 attempts) come within 10 yards of the line of scrimmage.

4. How will the Redskins use Adrian Peterson?

Despite signing with Washington in August, the 33-year-old running back already has dismissed any notion of being relegated to a rotational contributor role and seized the starting job.

But only once in the past four years has Jay Gruden’s offense ranked higher than 21st in rushing attempts, and integrating Peterson will require recalibrating.

5. Are Odell Beckham Jr. and Jalen Ramsey bound to produce some fireworks?

There might be no better individual matchup than the all-pro showdown between the Giants receiver and the Jaguars cornerback. Both are among the elite players at their position and have a well-established record of running hot in fierce competition.

Ramsey upped the intrigue with his assertion that Beckham was largely responsible for Eli Manning’s success, with the Giants quarterback returning serve by asking “who?” when informed of the comments.

Fellow Pro Bowl cornerback A.J. Bouye will also find himself in coverage against Beckham, but it’s the receiver’s clashes with Ramsey that will spark the most fanfare.

6. Can Deshaun Watson land a knockout punch against Tom Brady?

In the second start of his career, Watson came within a minute of dethroning the then-defending champions last season before Brady put New England over the top by capping an eight-play, 75-yard drive with his fifth touchdown pass of the day.

Going toe-to-toe with the eventual MVP was one of the many accomplishments that built hopes for Watson before a torn ACL cut his season short.

7. Will Earl Thomas’ return help the Seahawks’ revamped defense hold together?

The Legion of Boom is no more, as Richard Sherman and Kam Chancellor are among the key figures no longer with a once-formidable unit.

But Seattle is getting one of its stars back in Earl Thomas, the three-time allpro safety who on Wednesday ended his offseason-long holdout. Even though his return is a game changer for an overhauled secondary, there’s only so much he alone can do if the rest of the group can’t hold firm.

8. Will Jon Gruden prove the doubters wrong?

Skepticism is surging in Oakland after Gruden resolved a standoff with Mack by sending the former defensive player of the year to Chicago. With a defense that ranked No. 26 last year now missing its cornerstone, the Raiders have a murky outlook for 2018.
