ALAMEDA — The Raiders had the league’s No. 6 offense in 2016, so naturally the majority of their off-season moves have centered on improving … the offense.

Yes, at least for appearances sake, the Raiders have gone all-in on being an offensive juggernaut that hopes to outscore its opponents in 2017.

The Raiders did their share of that last year when they went 12-4 while putting up 26 points per game. The feeling was that improvements to the 26th-ranked defense — along with a healthy Derek Carr, of course — would push them closer to contention.

Instead, out went offensive coordinator Bill Musgrave, with quarterbacks coach and pupil Todd Downing elevated to the role of signal-caller.

In free agency, the Raiders added tight end Jared Cook, wide receiver/return special Cordarrelle Patterson and right tackle Marshall Newhouse, then signed E.J. Manuel to add a veteran to compete with Connor Cook at backup quarterback.

“I’m not surprised,” center Rodney Hudson said of the team’s focus on adding offensive pieces. “Teams are always trying to get better. No matter how good you are or how well you did, you always want to get better.”

All of those acquisitions could end up being dwarfed if and when the Raiders agree to terms with retired running back Marshawn Lynch and work out a trade with the Seattle Seahawks to bring the Oakland native to the Silver and Black.

“He’s one heck of a football player and I hope to play with him,” Carr said of Lynch. “You always need more good players. But with that said, I am focused on who is here. I want to take this group and win the Super Bowl with this group that is here and then as we add pieces, we’ll hug them up and bring them in just as a family and treat them the same way that we do with all of our other teammates.”

The Raiders haven’t completely forgotten about their defense. Next week’s draft should focus heavily on that side of the ball and the addition of assistant head coach for defense John Pagano could be that under-the-radar acquisition that pays dividends — and maybe on both sides of the ball.

Carr said Monday he’s looking forward to picking the brain of Pagano, the former Chargers defensive coordinator.

“To have a mind where his whole mind was to watch me on film and think, ‘How do I stop him? How do I defeat him? How do I embarrass him?’ and now to go to him and say, ‘What do you have on me? What are your notes? Let me work on those things,’ is something that not a lot of people get,” Carr said.

With those notes in hand, Carr will hope to further expand his game under Downing.

Carr said there could be some minor changes to terminology — “some things that click in his brain so we can call it faster” — but most changes won’t be noticeable to until they start game planning in August.

“I think then you’ll get his feel, you’ll get more of his spin on things as that time comes,” Carr said. “It’s not like we’re scrapping everything because we’re not. We had great stuff. Coach Musgrave is a great coach. He had great plays. We’re not throwing all that stuff away. As coach Downing would say, we’re just going to turn things here, change little things here, whatever we can do to get better and just keep going forward.”

Carr, like Hudson, wasn’t surprised to see the Raiders add more weapons and he’s particularly excited about adding Cook to the tight end group that includes stud blocker Lee Smith and Clive Walford, a third-year player the Raiders are still hoping emerges into a consistent weapon.

“When you add a guy like that, people look at your roster, ‘Do you need it?’,” Carr said. “But it’s just another good player that wanted to come play with us. Now we go 12-personnel, Clive and Jared, our two receivers and our running back and our fullback out there on the field, those aren’t easy matchups for people to cover.”

Who will that running back be? If it’s not Lynch, the Raiders will aim to add a power back in the draft. But there is an expressed confidence in returners DeAndre Washington and Jalen Richard, who both flashed at times during their rookies seasons backing up the departed Latavius Murray.

“Those guys can play,” Hudson said. “Latavius was out a few games last year and those guys stepped up, played well. They pick up stuff really well. Smart kids. They learn.”
