[2] McCann wrestled collegiately for the Iowa Hawkeyes where he only lost three matches in three years while winning three Big Ten and two NCAA titles.

McCann was inducted, as a Distinguished Member, into the National Wrestling Hall of Fame and Museum (USA) in 1977.

McCann was appointed as the executive director of Toastmasters International (TI) in March 1975, having accepted the position in February.

A decade earlier he had already discovered the benefits of the TI program, when he joined the Oil Capital Toastmasters club in Tulsa, Oklahoma, upon the suggestion of Bill Borders, a friend and former national wrestling champion.

In August 2005, McCann sued a large number of companies in the Superior Court of Los Angeles County on a variety of product liability theories.

The Court of Appeal eventually did rule for Foster Wheeler and against McCann on that issue, in an unpublished decision released on November 30, 2010.

The state supreme court denied review on February 16, 2011, thus bringing McCann's lawsuit to an end after over five years of litigation.
