When you think of the Houston Rockets' iconic jersey numbers, Hall of Famers like Hakeem Olajuwon or Clyde Drexler might come to mind. But every number tells a story, and jersey No. 12 has a unique chapter that begins with a future coaching legend on the court.

Rick Adelman, now enshrined in the Basketball Hall of Fame for his brilliant coaching career, started his NBA journey wearing Rockets red and yellow. Selected 79th overall in the 1968 draft by the then-San Diego Rockets, Adelman laced up his sneakers for the franchise's formative years.

As a guard for the Rockets from 1968 to 1970, Adelman was a steady presence, averaging 6.7 points, 2.7 rebounds, and 3.1 assists per game while exclusively wearing the No. 12. His tenure bridged the team's move from San Diego to Houston in 1971, making him a part of the franchise's foundational history.

While his playing stats were solid, Adelman's true legacy would be written from the sidelines. After being selected by the Portland Trail Blazers in the 1970 expansion draft, he eventually transitioned to a coaching career that would see him win over 1,000 games. It's a fascinating piece of Rockets lore—the number worn by a player who would later become one of the NBA's most respected tactical minds.

So, the next time you see that No. 12 Rockets jersey, remember it represents more than just two seasons of play. It's the origin story of a basketball lifer whose impact on the game spanned decades, beginning right here in Houston.
