Everything is going to come out for the Packers and Broncos when they square off Sunday night in Denver.

Both teams are among the best in the NFL — both enter at 6-0 — but both also seem to be surviving by refusing to acknowledge their dirty little secrets. The Denver offense has not appeared to be very good, and the Packers are facing similar problems.

For Green Bay, it’s not that there’s a sudden lack of weapons or Aaron Rodgers no longer has talent. The issue is that he has been forced to operate behind a weak offensive line and, well, there have been some injuries at receiver that the Packers have had to contend with. If that continues to be a problem Sunday, the Broncos, who have 26 sacks, could make it a long day.

For Denver, Peyton Manning hasn’t looked like himself this year. He has only completed 61.6 percent of his passes for 1,524 yards with seven touchdowns and 10 interceptions. It has been staggering to see. In his last start against Cleveland, he connected on 26 of 48 passes for 290 yards with a touchdown and three interceptions.

If Manning isn’t sharp this week, it might not matter how well the Denver defense performs. At some point, Rodgers and the Packers are going to move the ball and put up points. Manning is going to have to do enough to keep things close so Denver has a chance to win.

Someone is going to get exposed. Nothing can stay in the dark forever in the NFL.

But then again, maybe this game will expose the flaws on both sides.

NICK’S PICKS: Underhill’s top five teams (this week)

1. Patriots (7-0)

The Patriots knew they weren’t going to be able to run the ball against the Jets last week. So they didn’t run at all and still picked up a 30-23 win.

2. Packers (6-0)

They have some issues on offense, but you have to think those will eventually get sorted out. Until someone beats them, the Packers remain here.

3. BENGALS (6-0)

OK, so we’ve been slow to hop on the Andy Dalton train. We’re buying in ... for now. But expect the Steelers to play this team tough.

4. Panthers (6-0)

It doesn’t matter if you believe in their offense or how you feel about Cam Newton. The Panthers have a legitimatedefense and are finding ways to win.

5. Broncos (6-0)

Denver is still hanging on. Peyton Manning keeps having issues that don’t appear to be going away, but the Denver defense is legit. Like Carolina, they keep winning.
