I got this from a Terry Douglass piece in the GI paper: Between 1971 and 1988 (18 seasons, 19 games), OU and NU played 15 times when both teams were ranked in the top ten. I can't imagine that any other rivalry could come close to matching that. http://www.theindependent.com/stories/120206/hus_oldtimes02.shtml -- Dick Karre dkarre at comcast.net
