Junkie, the highest attendance bump trends towards the first game of the season regardless of opponent or day. So if we have an FCS game the opener in terms of attendance should be the first home game, its a 2-3 thousand bump.
Weekday nights seem to do better (my theory is those aren't against OU or OSU games and we get a few thousand casual fans who go to Stillwater or Norman usually).
Minn was a great crowd and I recall several people (no scientific polling) attending games that year who did so after experiencing the thurs night opener. It was also on Espn.
LEC, I thought so too, but the Wed night game (middle of the year game) was only 20,000 plus. I put up our best attended home conference game on all of the years and made notes about other things that may have effected attendance that we talked about, win streaks, big wins, losing streaks, coaching changes, bowl games, and if a specific opponent we mentioned was on there (Houston, BYU, La Tech, UL Monroe, etc)
