The games that day are
Ohio @ Kent State
Central Michigan @ Toledo
Northern Illinois @ Eastern Michigan
Western Michigan @ Bowling Green
Buffalo @ Akron
Starting off, the Buffalo @ Akron game is already scheduled for STO. Terrible game, anyways.
Western @ BG is meaningless, so I'd strike that.
Then you have three games with potential division title contenders. Central @ Toledo seems like a poor choice, given that Toledo doesn't control its own destiny.
I genuinely think it would have to come down to
NIU @ EMU, or Ohio @ Kent. Our game seems like it has a much better chance of being compelling (read: competitive) to me, and I would guess that would be the choice, unless they have solid data on ratings that would sway them towards the NIU game.
Regardless, I would think whichever of those two isn't on the U ends up on 3.
Just my guesses.
