The NBA's opening night has always been all about a celebration of the previous season.
The short slate of games are capped off at the home arena of the defending champions, where prior to tip-off, the title holders will witness the unveiling of their championship banner and players receive championship rings.
More often than not, the night ends with the reigning champs adding to the festivities by winning their season-opener. Sometimes, they have to work hard for the win, and sometimes, they blow by their opposition.
But, every once in a while, there's the unexpected upset.
