query: What were the reasons for the Green Bay Packers to find a replacement for City Stadium in the 1950s?
answer: In the 1950s, the Packers needed a new stadium because City Stadium couldn't be expanded, and its amenities were below NFL standards.  Many teams refused to play there, and the NFL told the Packers to either build a bigger stadium or move to Milwaukee.
