I want to know the answer to the following question:
What is the only professional team from North carolina to have won a league championship?
All the background I'm provided with is that "North Carolina is home to three major league sports franchises: the Carolina Panthers of the National Football League and the Charlotte Hornets of the National Basketball Association are based in Charlotte, while the Raleigh-based Carolina Hurricanes play in the National Hockey League.". Is that enough to answer the question?
