The Portland Trail Blazers made their NBA debut as an expansion team in the 1970–71 season. In 1977, they won their first and only league championship, though they made subsequent Finals appearances in 1990 and 1992 during a stretch from 1983–2003 in which they dazzled foes in the playoffs every season. The success of their ’77 championship run sparked a streak of 810 consecutive sold-out home games between 1977 and 1995. This led them to move into the newly constructed Rose Garden Arena in 1995, where to this day, up to 19,980 fans cheer in appreciation of every Blazers basket and every dazzling referee hand signal.
