Before his unexpected death on July 4, former Tennessee Titan quarterback Steve McNair had continued his tradition of civic involvement by filming a public service announcement for the Tennessee Department of Mental Health and Developmental Disabilities, The City Paper has learned. Sources say the advertisement was filmed, and editors were working on taglines and voiceovers when the deaths were discovered. When asked about the existence of the PSA, the mental health department confirmed that the filming had occurred. ?We were developing a PSA but it never reached the point of being aired and it seems broadcasting it now is not only inappropriate but doesn't serve the community, his family or memory, or the issue we hoped the PSA would help address,? said Jill Hudson, the department?s communications director.
