GREEN BAY, Wis. -- There will come a time in Sunday's game in New Orleans when one of the two quarterbacks won't be able to keep up.

And it may be only because there's no more time left.

When Aaron Rodgers and Drew Brees get together -- and it's not often -- the scoreboard operator usually gets a workout.

Nearly two thousand passing yards and 211 points combined in the only three head-to-head meetings between those two giants of the quarterbacking world is evidence enough that the Green Bay Packers and New Orleans Saints appear headed for another shootout in the Superdome this Sunday night.

"You're not playing against him," Rodgers insisted on Wednesday. "This is the Saints against the Packers."

But that doesn't mean the Packers quarterback won't have to react to what Brees and the Saints' offense throws at him. Or vice versa.

In those three meetings, Brees has thrown for at least 300 yards and three touchdowns without an interception. However, Rodgers has the edge in Total QBR (see accompanying chart).

The three meetings were:

• 2008 -- Saints 51, Packers 29: On "Monday Night Football" in New Orleans, the Saints tied a team record for points (which they have since surpassed) and scored seven touchdowns. Brees threw for 323 yards and four touchdowns.

• 2011 – Packers 42, Saints 34: In the Thursday night season opener at Lambeau Field, Rodgers threw for 312 yards and three touchdowns, while Brees put up 419 yards and three touchdowns but was stopped on the 1-yard line on the final play of the game.

• 2012 – Packers 28, Saints 27: In Green Bay, Brees threw for 446 yards and four touchdowns, while Rodgers threw for 319 yards and four touchdowns with one interception. The Saints missed a field goal with less than three minutes remaining.

Those three games may play no role whatsoever on Sunday. But the way Rodgers has started this season, it's hard to envision a defensive struggle is in the offing. He has thrown 18 touchdowns and just one interception this season. In the Packer' four-game winning streak, they have averaged 36.3 points per game. That's better than their scoring average (35.0 ppg) in 2011, when they set the franchise record for points (560).

"The year that he's having has been, you just kind of shake your head," Brees said Wednesday on a conference call with reporters at Lambeau Field. "He’s so impressive. Anytime there's a guy like that on the other side of the ball, you know you have to be at your best and it seems like all the little things in a game like this, all the little details are magnified.

"It's not one of these, 'Hey, we've got to be perfect.' Nobody is perfect. But you have to be pretty darn close. You have to be as good as you can be to have a shot at these guys when he's pulling the trigger on the other side."

In spite of the Saints' struggles in their 2-4 start, their offense has been as explosive as usual at home. In their two games at the Superdome (both victories), they have combined for 907 yards and 57 points.

"It's easy to say, "Well, you start with both teams [which] have had good offenses,' yet just as we say that, you can find yourself in one of those 17-13 games," Saints coach Sean Payton said.

That hardly seems possible, but both Payton and Packers coach Mike McCarthy said Wednesday that they have no preconceived notions about the way the game will play out. McCarthy said Wednesday that the plan in every game is to "shoot all your bullets. Hopefully, you're hitting them and they're not hitting you."

"If it ends up being a shootout, we've got to be prepared to do that," Packers right guard T.J. Lang said. "And I think we are every week [with] the amount of production that we've been having. I hate predicting games like that, saying it's going to be a shootout or a defensive battle. We've got to be prepared to do whatever it takes on game day."
