HENDERSON — When the Raiders acquired Chandler Jones in March, the move was expected to relieve the pass-rushing stress from Maxx Crosby and force opposing offenses to pay attention to both defensive ends.

That hasn’t happened.

Crosby has produced has been forced to constantly find his way through double teams and other roadblocks because Jones hasn’t provided enough pressure on the other side.

That’s part of why the team’s pass rush has been nearly nonexistent. They are last in the NFL with 3.24% of sacks coming on opposing passing attempts. And that’s with Crosby tied for 10th in the league with seven sacks; the rest of the team has three combined.

Jones has half a sack, just a season after he registered 10 1/2, with five coming in the season opener against the Tennessee Titans, accounting for nearly half his total.

Still, the Raiders were expecting more production from Jones, but it’s not all on him. The Raiders haven’t generated pressure from their interior line, either, and it’s led to opposing quarterbacks having more than ample time to find open receivers.

The result? Those quarterbacks have an average passer rating of 107.0 — a league best — against the Raiders (2-7), who on Sunday hit the road to face the Denver Broncos (3-6).

To put that into perspective, Kansas City Chiefs quarterback Patrick Mahomes is the NFL’s career leader with a 105.8 rating.

“Rushing and cover works together,” linebacker Denzel Perryman said. “If the quarterback has all the time in the world back there to throw, the rush has got to get home. If the quarterback gets the ball out quick and the rush can’t get there, that means we’ve got to cover longer.”

Sunday’s 25-20 loss to the Indianapolis Colts was the perfect example of the Raiders’ struggles. Indianapolis entered the game with 35 sacks allowed, including nine the week before against the New England Patriots.

The Raiders deactivated three interior defensive linemen, which coach Josh McDaniels later intimated had to do with disciplinary reasons. The move left the Raiders short-handed on the D-line.

It showed, even as Colts interim coach Jeff Saturday chose start Matt Ryan, a quarterback whose mobility doesn’t remind anyone of Mahomes or Kyler Murray. But Ryan was sacked just once — by Crosby, of course — and later burned the Raiders with a career-long 39-yard run to set up the winning touchdown. He also passed for 222 yards with a passer rating of 109.5.

“I thought they mixed in some different things relative to the way they were throwing the ball,” McDaniels said. “The (run-pass option) stuff, when you throw those, you’re kind of playing run while they’re throwing it. Those are some things that obviously your pass rush is a little limited there.

“I thought they mixed in some of the quick game stuff that the ball was coming out pretty quickly, which usually limits the rush and the production. We have to do better on the downs that we can do better on, if we can create some third-and-longs, some obvious passing situations to be able to provide more rush.”

The Raiders took a step to improve their play up front by signing tackle Jerry Tillery, a 2019 first-round draft pick who was with the Los Angeles Chargers before being waived Monday. He had 4 1/2 sacks last season, but only one through seven games this year.

Maybe Tillery will help — it would be difficult for the pass rush to be worse.

“Sometimes (sacks) come in bunches, and sometimes there’s streaks where they don’t happen,” McDaniels said. “I’d say, right now, we’re in one of those streaks for whatever reason. There have been opportunities. It’s not like we haven’t had chances.

“How do we improve that collectively, and adding Tillery, does that help us? Yeah, hopefully. We’ll see. But that was the intent on it, is maybe we can add another guy that has some disruption inside, maybe people pay a little less attention to our ends. And that’s a choice that obviously every offense is going to need to make.”
