In the early 1960s, Steadman worked with businessman
Lamar Hunt to establish the
American Football League and the
Dallas Texans. In
1963 the team moved to
Kansas City, Missouri when Steadman and Hunt negotiated with Kansas City Mayor
H. Roe Bartle to move the Texans to Kansas City as the Chiefs.
Truman Sports Complex In 1967, Kansas City was considering replacing its aging
Municipal Stadium with a new multi-use stadium for both its baseball and football teams. Denver self-educated architect
Charles Deaton suggested to Steadman that the teams would be better served if each sport had its own stadium that was configured to its unique demands but that the complex reduce costs by sharing parking and highway expenses. The architect firm
Kivett and Myers perfected the plan (adding a rolling roof) and voters approved it. (The rolling roof, however, was never added.)
Arrowhead Stadium opened in 1972 alongside
Royals Stadium (now known as Kauffman Stadium), which opened in 1973. The rolling roof was not to be built but the concept established Kivett and its successors in Kansas City as the dominant architects for almost all single-purpose
major league baseball and
football stadiums that have been built since. In 2005, the rolling roof plan re-emerged as part of Kansas City's bid to host
Super Bowl XLIX, but the measure failed in the polls. ==Chiefs organization==
