The second week of the NFL season prevents a much stiffer test for the Chicago Bears, who exploited a young and inexperience Indianapolis Colts team in Week 1.
The test comes via NFC North rival Green Bay, which was bested by the San Francisco 49ers at home in their season opener.
The two teams have the oldest rivalry in the NFL, and last year the Packers swept the bears despite Lovie Smith typically presenting a very difficult out for Mike McCarthy and his teams.
