Some context: Arnold Jacob Auerbach was one of the four children of Marie and Hyman Auerbach. Hyman was a Russian-Jewish immigrant from Minsk, Russia, and Marie Auerbach, nee Thompson, was American-born. Auerbach Sr. had left Russia when he was 13, and the couple owned a delicatessen store and later went into the dry-cleaning business. Little Arnold spent his whole childhood in Williamsburg, Brooklyn, playing basketball.
Auerbach died of a heart attack on October 28, 2006 at the age of 89. NBA commissioner David Stern said, "the void caused by his death will never be filled" and players Bill Russell, K.C. Jones, John Havlicek and Larry Bird, as well as contemporaries like Jerry West, Pat Riley, and Wayne Embry universally hailed Auerbach as one of the greatest personalities in NBA history. Bird stated "Red shared our passion for the game, our commitment to excellence, and our desire to do whatever it takes to win." Auerbach was survived by his two daughters, Nancy and Randy. Auerbach was interred in Falls Church, Virginia at King David Memorial Gardens within National Memorial Park on October 31, 2006. Attendees included basketball dignitaries Bill Russell, Kevin McHale, Danny Ainge, and David Stern.  During the 2006-07 NBA season, NBA TV and NBA.com aired reruns of Auerbach's four-minute instructional videos known as "Red on Roundball" previously aired during NBA on CBS halftime shows in the 1970s and 1980s, and as a testament to his importance in the Boston sports world, the Boston Red Sox honored Auerbach at their April 20, 2007 game against the New York Yankees by wearing green uniforms and by hanging replicated Celtics championship banners on the "Green Monster" at Fenway Park. Boston won 7-6.  Prior to Boston's season opener against the Wizards, his signature was officially placed on the parquet floor near center court, thereby naming the court as "Red Auerbach Parquet Floor." The ceremony was attended by his daughter Randy and some of the Celtics legends. The signature replaced the Red Auerbach memorial logo used during the 2007 season.

Some context: Hardy was born in Cameron, North Carolina, the son of Gilbert and Ruby Moore Hardy. He is the older brother of Jeff Hardy. Their mother died of brain cancer in 1986. Hardy played baseball as a child and throughout high school, but had stopped by his senior year.
Shortly after the departure of Matt and Jeff from TNA was made public, Matt's wife, Reby, went on a social media tirade in which she repeatedly slammed TNA, the company's new management and the way in which contract negotiations between the company and the Hardy family were conducted. A few weeks following this, the bad blood between the two sides intensified, so much so that the new management of TNA (now renamed Impact Wrestling) Anthem Sports & Entertainment issued a cease and desist letter to The Hardys' new promotion Ring of Honor (ROH), in which Anthem essentially ordered ROH as well as any broadcasting company airing ROH's 15th Anniversary pay-per-view show (on which The Hardys were to participate in a match) to not in any way speak of, indicate or acknowledge the existence of the Broken Matt and Brother Nero characters and instead to refer to The Hardys as simply Matt Hardy and Jeff Hardy. The issue with this is that while The Hardys were in TNA, they had full creative control over the Broken gimmick, with them even filming their own segments to air on TNA programming in some circumstances, thus making the Hardy family (in their belief) the owners of the Broken gimmick. It is believed that civil litigation will follow and a potential court hearing will take place regarding the final outcome on who owns the Broken gimmick: Anthem or the Hardy family. Until then, the status of the Broken gimmick remains undecided. Despite this, Matt continues to use the Broken gimmick through his social media accounts, but neither him or Jeff use the Broken gimmick at any professional wrestling shows for ROH or on the independent circuit, presumably until the results of the expected legal proceedings have been finalized.  Newly-appointed Impact Wrestling President Ed Nordholm credits the invention of and the vision behind the Broken gimmick to Jeremy Borash, Dave Lagana and Billy Corgan, and while Borash specifically had the most input into the gimmick of the three aside from Matt, the Hardy family deny that Borash was the sole person behind the gimmick. In November 2017, Impact Wrestling changed their policy, allowing all talent to retain complete ownership over their intellectual property, essentially forfeiting ownership of the "Broken" character to Hardy.  On January 31, 2018, the legal battle officially concluded when Matt legally acquired ownership of all trademarks related to the Broken universe and the Broken gimmick, which includes 'Broken Matt', 'Brother Nero', 'Broken Brilliance' and 'Vanguard1'. Matt is now able to use the Broken gimmick as he sees fit, regardless of the promotion he competes in with the one caveat being that the promotion green-lights the use of the gimmick in that promotion, which includes major domestic U.S. promotions such as WWE or ROH.
