Zimbalist on League Consultants, 2004:

Andrew Zimbalist, NewsHour with Jim Lehrer, 12/22/04:

Practically every stadium that's come on stream in the last 20 years in the United States has been accompanied by a consulting report - these are hired-out consulting companies - that are working for the promoters of the stadium. They engage in a very, very dubious methodology. They make unrealistic assumptions and they can produce whatever result they want to produce.

Hat-tip to Neil deMaus.
