Texas Triangle (Dallas, Houston, San Antonio)

National Basketball Association teams often speak of the tough “Texas Triangle” road trip against the Dallas Mavericks, Houston Rockets and San Antonio Spurs. The term “Texas Triangle” was used by the Missouri Pacific Railroad as early as the 1930s, but the term became popular in the NBA in the early 1990s.
 
The “Texas Triangle” is also sometimes called the “Golden Triangle” or “Texas Trifecta” or “Texas Three-Step.”
