Another thing that I think is important to Duke basketball is all about their championships. So the first thing that I was wondering about their championships is how many ACC championships that they have won. So far they have won 19 ACC championships. Another thing that I was wondering about was how many conference championships that they have won. For their regular season they had won 22 championships, and in the conference tournament they had won 23 championships. One other thing that I was wondering about Duke's championships is how many NCAA championship appearances and wins has Duke had. So far Duke basketball has had 11 appearances in the National Championships Tournament. The good part about this is, Duke has won 56 National Championships and there is still more to come.
