Marqise Lee isn't going to sugarcoat the Jaguars' offensive struggles. The team's Week 12 loss to the Arizona Cardinals highlighted the unit's woes.

Missing three offensive starters, the Jaguars failed to consistently move the ball for the second-straight week.

"It is what it is," Lee said. "The offense has been struggling all year."

The wide receiver was held to just one catch for 13 yards against Arizona.

The passing game provided just 160 yards. The Jaguars' running backs produced just 29 rushing yards.

While quarterback Blake Bortles was able to piece together three scoring drives, the offense's early struggles put the team in a deep hole.

Typically aided by multiple takeaways from the defense, the offense didn't get the weekly turnover support until the fourth quarter.

The Jaguars' defense produced a touchdown off a sack-strip by defensive end Yannick Ngakoue with 12:19 left in the game. The touchdown and an extra point put the Jaguars up, 17-16.

The lead lasted for just over three minutes. The Cardinals came roaring back with a 52-yard touchdown completion off a blown coverage from the Jaguars' defense.

When it came time for the Jaguars' offense to step up in the final minutes, the unit failed to produce. Wide receivers dropped passes and Bortles threw a late interception.

"I know there's going to be times when the offense has got to step up and this game was the time," Lee said.

"We failed the defense and we've got to pick it up because I know the defense is going to continue to play their butts off and the offense is going to have to step up and that's what we're going to have to do."

Lee has been the focal point of the receiving game since veteran Allen Hurns went down with an ankle injury in Week 10. He has been joined by rookies Dede Westbrook and Keelan Cole.

While his partners in the receiving game are young, Lee feels the duo could provide some big plays during the regular season's home stretch.

"Even if [the ball is] not coming to me, I feel like Dede can make those plays, Cole can make those plays too," Lee said. "Everybody on this team is capable, just got to go out there and do it."

The Jaguars' receivers need to become more reliable. Bortles needs to become more consistent with his accuracy.

Until both parties accomplish those two goals, the offense will continue struggle.

"We understand how things work around here," Lee said. "The run game is going well and the receiving game is kinda suspect."

The Jaguars' receivers will look to bounce back during the Week 13 rematch against the Indianapolis Colts. Jacksonville put up 330 passing yards in the Week 7 outing in Indianapolis.
