Moving into the bargaining phase - our history against other B1G opponents

Like a lot of people, I don't have a big problem with Maryland or Rutgers per se; I just dislike having 14 teams because that means having two more league opponents that we won't play in any given year (unless we expand the conference schedule, which I'd really like to see).  But I was thinking about this when I saw what our all-time record against Iowa was (41-13-4) - a school with whom we have shared a conference for a century.  It turns out that the custom of playing everyone, or just about everyone, in the conference is actually not that old.  Here are our all-time series against B1G opponents:

Ohio: 58-44-6 (108 meetings)

MSU: 68-32-5 (105 meetings)

Minnesota: 72-24-3 (99 meetings)

Illinois: 69-23-2 (94 meetings)

Northwestern: 53-15-2 (71 meetings)

Wisconsin: 49-14-1 (64 meetings)

Indiana: 52-9 (61 meetings)

Purdue: 44-14 (58 meetings)

Iowa: 41-13-4 (58 meetings)

PSU: 10-6 (16 meetings)

Nebraska: 4-3-1 (eight meetings)

So it seems that historically, there have only been four teams we've played on a truly annual basis: Ohio, MSU, Minnesota and Illinois (I guess that's why they consider us a rival).  That makes sense when you consider that for a long time, the football season was only eight or nine games long, and not all of those were league games.   Most of our games against schools like Wisconsin, Indiana and Purdue must have occurred in the last 30 years or so, when we started playing near-round robin schedules.  Before then it was almost like they weren't in our conference.  This is the direction in which we are going now.  Is it ideal?  No, but we have been there before.
