B1G/Pac 12 Matchups Matrix

Because I am nothing if not insanely curious about this, the following is a matrix of the last time each Big Ten school faced each Pac 12 school, along with the essential range of the number of times they have played since 1936.  There are eight matchups that have never occurred, those are in red with a white 0 in the cell.

This, this is what I do.

Light pink is a matchup that has only occurred once.
Deep Yellow (old school maize if you will) are matchups that have occurred two to four times.
Yellow are matchups that have occurred five to nine times.
Light green are matchups that have occurred 10-19 times.
Light blue are matchups that have occurred 20-49 times (in this case, just OSU/USC)
The Darker Blue are matchups that have occurred 50+ times (which is Colorado/Nebraska from their old Big 8/Big XII days.)

I'll have more on "dream" initial matchups in 2017, but for now, make use of this data as you see fit.
