Interesting. That is for two-way ties (or so it says).
I wonder if they have a metric out there (I suppose they do) for ties involving three or more teams?
With an 18 team conference, and only 9 conference games (doesn't create a lot of opportunities for "separation"), it may be just as likely (maybe even more likely) that ties would involve more than two teams.
I suppose you could use similar metrics, but the graphic from the B10 Network specifically cites "two teams". Maybe a typo on the part of B10 Network? IDK
