In the lead-up to training camps, USA TODAY Sports will be breaking down the key questions facing each NFL team. Today, we look at the Oakland Raiders:

How will Jon Gruden fare in his return to coaching?

Gruden was never far from the game in his decade away from coaching given his broadcasting gig with ESPN, his offseason meetings with players and his extensive film work, but it has been a long time since he last ran a training camp or installed game plans.

And this is the first time Gruden has coached a roster full of Millennials and in a football world full of new technology and analytics. Can he resist his urges to try to do things the same way he did in the mid-2000s?

"Obviously, you have to change a little bit. But I think the roots, the foundation of what I know, is going to stay in place," Gruden said at this year's NFL scouting combine.

Gruden's enthusiasm and intensity should make him immediately popular with his players. His innovative, offensive mind should translate well with young, talented quarterback Derek Carr.

Carr and the offense get back on track?

Carr and the offense took a step back after their breakout season in 2016. The young passer dealt with a midseason back injury (he missed one game), and his touchdowns were down (from 28 to 22) and his interceptions were up (from six to 13) from when he helped the Raiders earn a wild-card spot a season before.

Carr has a revamped receiving corps. Michael Crabtree is gone, but Bryant and former Packer Jordy Nelson join No. 1 receiver Amari Cooper. The Raiders still have some pieces in place on the offensive line, especially center Rodney Hudson and left guard Kelechi Osemele, and look like they have a new starting right tackle in first-round pick Kolton Miller, which should help Carr and the running game return to form.

Marshawn Lynch remains on the roster, but he has to show he still is deserving of his role at 32.

Will front office remain the same for foreseeable future?

General manager Reggie McKenzie earned praise for how he helped rebuild the Raiders, thanks to smart draft picks on Carr and pass rusher Khalil Mack. But with the massive power that came with Gruden's $100 million contract, it's fair to wonder how much longer their partnership will last.

The draft showed Gruden is wielding power, with the addition of several high-risk/high-rewar­d-type players, such as Bryant, who served multiple drug-related suspensions while with the Steelers, or former Michigan defensive lineman Maurice Hurst, who was diagnosed with a heart condition.
