GREEN BAY, Wis. -- When Mike McCarthy hears his quarterback talk about the need to do something different "schematically" and another offensive player suggest they need to be more "creative," the Green Bay Packers coach understands.

That doesn't necessarily mean he thinks radical alterations are needed to turn around an offense that isn't used to struggling.

"I think it represents frustration," McCarthy said. "As far as our scheme and the way we give players opportunities at the line of scrimmage, the adjustment components, the decision-making components at the line of scrimmage, I think that's really a reflection of frustration between players and coaches. The fact of the matter is, we're not executing and being able to get more into the things you like to do.

"Offensively, you can say what you want, but I don't know how many great days you're going to have ... when you're at 50 plays two weeks in a row. I know I'm not complaining about the scheme. There's a lot more to be focused on."

McCarthy and his coaching staff spent the last two days on another self-scouting project -- similar to what they do during the bye week -- to try to figure out a way to reverse some ugly numbers on offense.

Heading into Sunday's game at the unbeaten Carolina Panthers (7-0), here's where the Packers (6-1) stand in comparison to the other 32 teams in several key offensive categories:

• Yards: 28th (332.1 per game)

• Rushing yards: 12th (122 per game)

• Passing yards: 27th (210.1 per game)

• Points: 10th (24.9 per game)

• Yards per play: 10th (5.71)

The Packers have never finished a season outside the top 10 in passing yards since Aaron Rodgers took over as the starter in 2008 and have finished outside the top 10 in total yards only once in that stretch (they were 13th in 2012).

"We just have to take a look what we're doing offensively," Packers right guard T.J. Lang said. "It's kind of been a problem for us all year. Our defense has hid a lot of our flaws on offense for us winning some games for us.

"Offensively, we've got to find a way to get better in the run game, protection, getting guys open, whatever it is."

Then Lang said they need to "find a way to be more creative and get back to playing the way we're used to playing, getting those big plays and being a productive, consistent offense."

That combined with Rodgers' comment after the loss to the Denver Broncos that "schematically we've got to probably do some different things" suggests the players are looking for changes from McCarthy and his staff.

"Our players are good enough; our scheme is good enough," offensive coordinator Edgar Bennett said. "We feel like we have everything in place. We're still 6-1. We'll continue to improve, and we'll certainly improve from Sunday night's performance."

Neither Rodgers nor Lang was putting it all on scheme. Rodgers said "execution-wise we need to get open and complete passes," while Lang added that "this group has a lot of pride, and I know guys are going to come in ready to work."

Both players made their comments in the postgame locker room immediately following Sunday's loss, which was the last time players were available to the media, so certainly frustration played a factor.

"We have very good players, we have good schemes," McCarthy said.
