In 1967, one of the ABA’s charter franchises was awarded to a group in Kansas City, Missouri headed by Southern California businessman James Trindle. However, Trindle was unable to find a suitable arena in the Kansas City area. League commissioner George Mikan suggested moving the team to Denver. After agreeing to name Denver native and former NBA player Vince Boryla as general manager, Trindle moved his team to Denver as the Denver Larks, named after the Colorado state bird. The Trindle group was severely undercapitalized, leading Mikan to order the Larks to post a $100,000 performance bond or lose the franchise. Hours before the deadline, Trindle sold a two-thirds controlling interest to Denver trucking magnate Bill Ringsby for $350,000. Ringsby then renamed the team the Rockets, after his company’s long-haul trucks.

The team’s first year on the court (1967 – 1968) had to be considered a successful one, especially attendance-wise. Unlike other ABA teams, Denver started out very slow at the gate. Only 2,748 fans attended the Rockets’ first home game against the Anaheim Amigos. But, attendance picked up over the course of the season, as Denver residents gradually warmed up to their new pro team. In their inaugural season, the Rockets averaged a healthy 4,128 fans per game. This figure encouraged the Ringsbys and confirmed that Denver could, indeed, support a pro basketball franchise.

On the court, the Rockets were good, but not great. The Rockets had two powerful offensive weapons. Larry Jones (from Wilkes-Barre of the Eastern League) soon served notice that he was one of the quickest, deadliest guards in the ABA. At times, he was a scoring machine. On November 28, 1967, he scored 52 points at home against the Oakland Oaks. He averaged 22.8 points per game that first year, and was named First-Team All-ABA. Despite Jones’ spectacular play, Willie Murrell (also from the Eastern League) was voted the team’s MVP. Murrell averaged 16.4 points and 9.0 rebounds for the season. Other original Rockets were Byron Beck (out of Denver University), Wayne Hightower (from the Detroit Pistons of the NBA), Lefty Thomas (from the Harlem Clowns), Julian Hammond (out of Tulsa), and Tom “Whammy” Bowens (a great leaper, out of Grambling).

After Denver’s playoff defeat at the hands of the Oaks, Denver’s front office knew it had to improve the team’s talent level. The Ringsbys contented themselves (and shocked the basketball world) by signing an undergraduate phenom from the University of Detroit: Spencer Haywood. The 6’9″ Haywood had played only one year of junior college ball (at Trinidad Junior College in Colorado), and one year of Division I basketball at Detroit. But, having averaged 32.2 points per game at Detroit (he was an All-America choice as a sophomore), and having sparked the U.S. Olympic Basketball Team to a gold medal performance at the 1968 Mexico City Summer Games, Haywood was bored with college ball. Despite protests from the NCAA and the NBA (and even some ABA owners), Haywood was allowed to play for the Rockets, even though he had not completed his four years of college eligibility. Haywood was the very first pro player to take this route. The Rockets publicly explained it as a “hardship” exception, designed to allow Haywood to provide for his large family (including his mother and nine brothers and sisters). Haywood’s presence made a huge impact on the 1969 – 1970 Rockets.

Haywood’s spectacular 1969 – 1970 rookie season gave Rockets fans cause for optimism for the 1970 – 1971 season . But, the season turned out to be a disaster for the franchise. In the fall of 1970, Haywood played only two exhibition games for the Rockets (scoring over 40 points in each). After those two games, he bolted the team because of a contract dispute. Haywood was upset because much of his salary was in the form of deferred (future) payments. The Rockets refused to restructure his contract, and Haywood decided to jump to the Seattle SuperSonics of the NBA. The Rockets filed several lawsuits to keep Haywood in Denver. For months, the Rockets stubbornly held out hope that Haywood would return to the team (for much of the 1970 – 1971 season, Rockets game programs still contained Haywood’s name in the lineup section). Denver eventually relented, and Haywood played 33 games for the Sonics in the spring of 1971.
