I graduated in 1978, too, just as someone above stated. This was the last year of 6 man at my high school. Fall of 78 began 5 man. There was a controversy and the summer before my senior year, we practiced 5 man, but that fall we went back to 6 man. So the first year of 5 man was 78-79 basketball season. I too have the newspaper clippings.
