Utah Governor Gary Herbert declared October 10, 2013 as "Jazz Bear Day" in recognition of his 20th season as the Utah Jazz' mascot, and also his countless hours of community and public service and his standing as an important citizen of Utah.  In 2006, Jazz Bear was inducted into the Mascot Hall of Fame.  The Bear has suffered many injuries while performing, including tearing his bicep and rupturing a tendon in his calf. The 1951 NBA All-Star Game was an exhibition basketball game played on March 2, 1951, at Boston Garden in Boston, Massachusetts, home of the Boston Celtics.  The game was the first edition of the National Basketball Association (NBA) All-Star Game and was played during the 1950–51 NBA season.  The idea of holding an All-Star Game was conceived during a meeting between NBA President Maurice Podoloff, NBA publicity director Haskell Cohen and Boston Celtics owner Walter A. Brown.  At that time, the basketball world had just been stunned by the college basketball point-shaving scandal.  In order to regain public attention to the league, Cohen suggested the league to host an exhibition game featuring the league's best players, similar to the Major League Baseball's All-Star Game.  Although most people, including Podoloff, were pessimistic about the idea, Brown remained confident that it would be a success.  He even offered to host the game and to cover all the expenses or potential losses incurred from the game.  The Eastern All-Stars team defeated the Western All-Stars team 111–94.  Boston Celtics' Ed Macauley was named as the first NBA All-Star Game Most Valuable Player Award.  The game became a success, drawing an attendance of 10,094, much higher than that season's average attendance of 3,500. The 1980 NBA draft was the 34th annual draft of the National Basketball Association (NBA).  The draft was held on June 10, 1980, before the 1980–81 season.  In this draft, 23 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players.  The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip.  The Boston Celtics, who obtained the Detroit Pistons' first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Utah Jazz were awarded the second pick.  The Celtics then traded the first pick to the Golden State Warriors before the draft.  The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season.  An expansion franchise, the Dallas Mavericks, took part in the NBA Draft for the first time and were assigned the eleventh pick in each round.  A player who had finished his four-year college eligibility was automatically eligible for selection.  Before the draft, five college underclassmen announced that they would leave college early and would be eligible for selection.  The draft consisted of 10 rounds comprising the selection of 214 players.  This draft has the distinction of being the first NBA Draft to be televised. The 1979 NBA draft was the 33rd annual draft of the National Basketball Association (NBA).  The draft was held on June 25, 1979, before the 1979–80 season.  In this draft, 22 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players.  The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip.  The Los Angeles Lakers, who obtained the New Orleans Jazz' first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Chicago Bulls were awarded the second pick.  The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season.  A player who had finished his four-year college eligibility was eligible for selection.  If a player left college early, he would not be eligible for selection until his college class graduated.  Larry Bird would have been eligible to join this draft class because his "junior eligible" draft status from being taken by Boston in 1978 would expire the minute the 1979 draft began, but Bird and the Celtics agreed on a 5-year contract in time to avoid that.  Before the draft, five college underclassmen were declared eligible for selection under the "hardship" rule.  These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier.  Prior to the draft, the Jazz relocated from New Orleans to Salt Lake City and became the Utah Jazz.  The draft consisted of 10 rounds comprising the selection of 202 players. The 2017–18 Utah Jazz season will be the 44th season of the franchise in the National Basketball Association (NBA), and the 39th season of the franchise in Salt Lake City.  On the 4th of July, Gordon Hayward announced he would leave the Jazz and sign with the Boston Celtics.
