Each conference round in the NBA playoffs is a best-of-seven series played in a 2-2-1-1-1 format...or the team with home-court advantage hosts games 1, 2, 5, and 7 while their opponent hosts games 3, 4, and 6.
However, the NBA Finals is a best-of-seven series is played in a 2-3-2 format...or the team with home-court advantage hosts games 1, 2, 6, and 7 while their opponent hosts games 3, 4, and 5.
What is the motivation behind using the 2-3-2 series format for the NBA Finals? Do factors of home-court advantage change in a 2-3-2 series format vs. a 2-2-1-1-1 series format?
