Why is "1969 ABA draft" trending?

Wikipedia Overview

The 1969 ABA draft was the third draft done by the American Basketball Association (ABA), an upstart rivaling league to the National Basketball Association (NBA) that they would eventually merge with as a part of the NBA a number of years later. This draft began on February 15, 1969, and was held in Bloomington, Minnesota and ended exactly two months later on April 15, 1969, with it being held in Charlotte, North Carolina, though they'd decrease the number of rounds back down to 10 rounds again similar to their inaugural draft year. Much like their first two drafts, this draft was also held as a "secret draft", with this specific draft also having an operation codename in mind called "Operation Kingfish", in which the two worst teams of the ABA by February 15 of that year, the New York Nets and Houston Mavericks, would acquire what was deemed the two best players of the draft period that year, Lew Alcindor from UCLA and Neal Walk from the University of Florida, and persuade them to join them over the two new expansion teams from the previous season, the Milwaukee Bucks and Phoenix Suns respectively, with Alcindor being the main prize in question. However, both teams would fail in acquiring the key players they deemed necessary to upgrade their quality of performance in order to effectively compete against the NBA at the time, which led to ABA commissioner George Mikan effectively resigning from his position following his failure to persuade Alcindor in particular to join the Nets instead of the Bucks for new Houston Mavericks/Carolina Cougars owner Jim Gardner in an interim period before Jack Dolph took over the position in the long-term, as well as led to an ownership change for the Nets with Roy Boe taking over that team instead.of Arthur J. Brown and the ABA moving their headquarters from the state of Minnesota to the New York City area akin to the NBA. Despite that failure, the period afterward would also be notable for the acquisition of undrafted sophomore Spencer Haywood, which led to the Haywood v. National Basketball Association Supreme Court case years later that would help modify both the ABA & NBA's own draft systems for years to come following Haywood's brief time with the ABA's Denver Rockets. Outside of Haywood, the best draft prospect from the ABA that stayed in the league during that year would be a late round selection named Mack Calvin. This also became the last draft that the Houston Mavericks would participate in under that name, as once the 1968–69 ABA season officially concluded for the Mavericks, they would officially move eastward to the state of North Carolina to become a regional franchise called the Carolina Cougars, taking on that franchise's entire history and draft stock in the process entering the rest of that draft period in April. Not only that, but it also became the last draft done by the defending champion Oakland Oaks since they would also move out east to become the Washington Caps following an accidental bankruptcy threat at hand, as well as the only draft done by the Minnesota Pipers since they would return to Pittsburgh, Pennsylvania after one year out in Minnesota to once again become the Pittsburgh Pipers.
