1. Refs swung towards home court
2. Cuse had home court advantage
3. Cuse had 25K fans (more than they will ever get) helping them beat duke, again @home
4. They beat duke at the end with duke having two of its best players in foul trouble starting around the 10 min mark, and eventually fouled out.
AZ beat Duke outright in regulation in a *neutral court (2/3 were easily duke fans) with all of their starters still in the game.
This is easy, I know who #1 is!
