I would say for die-hard fans the Draft is more exciting. However, for the fans of the two Super Bowl teams, the Super Bowl is more exciting. The thing I like about the draft is that EVERY team takes a part of it, and every team/fans can come out of it feeling like winners.
The draft is my life I have spent way too many hours at work making mocks and ranking players instead of working. If it was the Dolphins in the super bowl that would be nerve racking for me not exciting.
