It's probably more accurate to look at how many points teams got across the whole league rather than the two divisions, as if they were seeding for the MAC tournament. Based on pre-season polls they were expected to finish:
https://getsomemaction.com/news/2019/10/30/mac-announces-... 1) Bowling Green (69)
2) Toledo (69)
3) Buffalo (58)
4) N Illinois (52)
5) Ball St (51)
6) Kent St (43)
7) C Michigan (41)
8) Miami (37)
9) Akron (33)
10) W Michigan (23)
11) E Michigan (16)
12) Ohio (12)
Comparing that to reality, with the amount they missed by in parenthesis:
1) Akron (+8)
2) Bowling Green (-1)
3) Ball St (+2)
4) N Illinois (0)
5) Buffalo (-2)
6) Kent St (0)
7) Toledo (-5)
8) Ohio (+4)
9) C Michigan (-2)
10) W Michigan (0)
11) E Michigan (0)
12) Miami (-4)
I don't think missing by up to +/-2 is very big at all. So really they just missed: Akron +8 and Ohio +4 on the positive side, and Toledo -5 and Miami -4 on the negative side.
