In 1977, when DeRutte was playing safety, Kevin Delcambre was at defensive halfback, and maybe Doyle at the other halfback, there was a stat sheet hanging outside of the coaches offices in the old brick field house. The Indians had 25+ interceptions over the season. I do not recall the exact number, a 48 year memory is a little blurry. Maybe 26, but that had to be one of the all time season highs, if not the record.
Randy Johnson still holds the individual record of 14 interceptions in a season (1975). I suspect that would have also been a 20+ team total for that season.
