Kansas City Chiefs
History: Had it not been for construction cost overruns and project delays caused by a lengthy strike, the Truman Sports Complex, home to Arrowhead Stadium and its MLB counterpart Kauffman Stadium, may have had a rolling stadium roof that could cover either facility, as originally approved by voters in 1967. Despite the design changes, Arrowhead was still over-the-top impressive enough when it opened for the 1972 season that legendary Chicago Bears founder George Halas called it "the most revolutionary, futuristic, sports complex I have ever seen." And it just gets better; today the stadium is in the midst of renovation, which will include a new enclosed area on the club area, wider and more expansive concourses on all levels and an Horizon level with its own concession and bathrooms. On April 4, 2006, taxpayers in Jackson County, Missouri, approved a 3/8 cent sales tax that is expected to raise $425 million for improvements to the Sports Complex, including $325 million for Arrowhead. In addition, the Chiefs are contributing $125 million to the project. After 23 seasons of artificial turf, Arrowhead sported a grass playing surface for the first time in 1994. In 1999 all 33,975 seats in the upper level of the stadium were replaced, while all 35,277 lower-level seats and all 10,199 club level seats were replaced for the 2000 season.
