For each decade, name the teams in each of the "Big 4" North American professional sports (NFL, MLB, NBA, NHL) that won the most championships.
Seasons that start in one year and end in another are considered to belong to the decade in which they started. For example, the NFL season that started on September 1, 1979 and ended with Super Bowl XIV on January 2, 1980 is considered to belong to the 1970s, not the 1980s.
If multiple teams won the same number of championships, name any of them.
Not bad, I scored 23/28. I was right on all of the NFL teams. I missed only one MLB answer and only one NBA answer. Hockey was my downfall. Thanks for the quiz!
