Generally, Packers coach Mike McCarthy has been happy with how his team has practiced this season. What is happening during games continues to confound Green Bay, especially lately with its once-potent offense.

The Packers will need to figure out their problems in a hurry with a trip to surging Detroit coming up Thursday night.

"Let's make it clear — we've been successful here, and success, you don't own success, it's rented. And you've got to earn it each and every day," McCarthy said Sunday before practice.

This is another odd week for the Packers with back-to-back Thursday night games on the schedule. Drops have been a problem for receivers, who are also dealing with press coverage from defenses that don't have to worry about the Packers' best deep threat, injured star Jordy Nelson.

Davante Adams, who was lauded for his work in the offseason and preseason, hasn't had the expected jump in production to help make up for Nelson's absence. Adams was hobbled by a sprained ankle in Week 2.

"I think that's been hampering him a little bit but I don't think anybody's lost confidence in him," quarterback Aaron Rodgers said Sunday after practice.
