It was considered by many as WCW's answer to the World Wrestling Federation's annual Survivor Series pay-per-view event due to the main event WarGames match held during most of the Fall Brawl shows.  World Wrestling Entertainment have owned the rights to Fall Brawl since they purchased WCW in March 2001 and although they have not produced the event under the main banner, Ohio Valley Wrestling did use the "Fall Brawl" name during the time it was a WWE development territory.  In 2014, All WCW pay-per-views were made available on the WWE Network.

The season is best remembered when Carmelo Anthony made headlines on December 15 when he was involved in a brawl against the Knicks, allowing the league to suspend him for the next 15 games.

Anthony and newly acquired Iverson played their first game together on January 22, 2007 in a game against Memphis.  The Nuggets finished the year at 45-37, making the postseason for the fourth straight year.  However, they did not make it out of the first round, losing to the eventual champion San Antonio Spurs in five games.  Anthony and Iverson were voted to play in the 2007 NBA All-Star Game.
