to "oversaturate" the market by expanding too quickly. Hunt also attempted to purchase the NFL's Chicago Cardinals (now based in Arizona) franchise in 1959 with the intention to move them to Dallas, but was again turned down (the team moved to St. Louis, Missouri in 1960). In response, Hunt approached several other businessmen who had also unsuccessfully sought NFL franchises, including fellow Texan and oilman K. S. "Bud" Adams of Houston, about forming a new football league, and the American Football League was established in August 1959. The group of the eight founders of the AFL teams was referred to as the "Foolish Club". Hunt's goal was to bring professional football to Texas and to acquire an NFL team for the Hunt family. Hunt became an owner of the Dallas Texans and hired future hall-of-Famer Hank Stram as the team's first head coach. The team, along with the AFL, began play in 1960. Ownership and NFL merger As a response to the newly formed league and the presence of an AFL franchise in Dallas, the NFL quickly placed a new franchise of their own in Dallas, the Dallas Cowboys, who also began play in 1960. As a result, the Dallas Texans, despite being one of the more successful AFL teams in the league's early days, had little luck at the gate, as they had to compete with the Cowboys for fans. By the end of the 1962 season, Hunt concluded that Dallas was not big enough to support two teams, and began to consider moving the team. Kansas City became one of the contenders, as Hunt wanted a city to which he could easily commute from Dallas. To convince Hunt to move the team to Kansas City, mayor H. Roe Bartle promised Hunt home attendance of 25,000 people per game: Hunt finally agreed to move the team to Kansas City, and in 1963 the Dallas Texans were rebranded the Kansas City Chiefs. While the Chiefs' first two seasons had attendance not match the levels Mayor Bartle had promised, in 1966 average home attendance at Chiefs games increased and reached 37,000. By 1969, Chiefs' average home attendance had reached 51,000. In 1966, the Chiefs won their first AFL Championship (after having previously won it as the Dallas Texans) and reached the first-ever Super Bowl, which the Chiefs lost to the Green Bay Packers. The Chiefs remained successful through the 1960s, and
