GREEN BAY, Wis. -- Aaron Rodgers has not thrown an interception since Week 1. He owns the best touchdown to interception ratio (15 to 1) of any quarterback in the NFL this season. And only one team has averaged more points over the last three weeks than his Green Bay Packers (with a little help from their defense).

And they have won three straight after their 1-2 start.

All should be right with their offense.

Except that it isn't -- at least not in the minds of Rodgers and coach Mike McCarthy.

"I don't think we're on a roll yet," Rodgers said Wednesday. "I think we're playing OK, scored enough points to win, but we're still low in the league in yards per game, low in first-down percentage, low in a lot of stats -- yards per play, passing yards per game, rushing yards per game. We've got to play better on offense, but we've scored enough points on offense the last three weeks to win."

Rodgers is right about those numbers. They rank 26th in yards per game, 20th in first downs per game, 19th in yards per play, 20th in passing yards per game and 24th in rushing yards per game.

In Sunday's win over the Miami Dolphins, they eclipsed the 75-play mark on offense -- their average goal for every game -- for the first time all season.

Rodgers ranks tied for second in touchdown passes, second in passer rating and third in total QBR.

However, even some Rodgers' best categories historically aren't at their usual standard. His completion percentage (64.6) ranks 13th in the league and is on pace to be his lowest since 2009. His yards per attempt (7.51) is tied for 12th, well off the 9.2 mark he set in his MVP season of 2011.

Make no mistake about it: Rodgers is playing well, but ...

"I've seen him play better," McCarthy said. "I just think one thing from the standard that he's set and all the little things he's done at a high level, he's got a lot of good football in front of him. I mean, the way we're taking care of the football, the big plays and timely plays -- exceptional. No doubt about it. It's not really as much his individual performance I'm referring to. It's our focus this week offensively is we were not clearly as efficient as we want to be after six games. So that's a focus of ours, and it's part of the way we spent our time here the last couple days."
