There are 64 eligible teams right now. There are 30 ineligible. There are 37 teams still alive. It would take an absurd set of circumstances for Ohio to not get a bowl so it isn't much concern but teamranking's sum is up to 81.5 now.
I mentioned it before the MAC has 4 bowls that it has to fill with individual contracts (Detroit, Boise, Tucson, Bahamas). It also has 6 guaranteed slot overall including placement in an ESPN bowl. This is how the 2020-2025 bowl cycle is structured. There is more security here than bowl slots vs. bowl eligible.
After Buffalo as a probable 4th bowl eligible team the chances are limited for the others.
Buffalo 5-5 (Akron, Kent St)
Ball St 5-5 (Ohio, @Miami)
BGSU 5-5 (@Toledo, @Ohio)
Miami 4-6 (@NIU, Ball St)
Kent 4-6 (EMU, @Buffalo)
CMU 4-6 (WMU, @EMU)
If BG and Ball State both win out they hit 7 wins tying the Bobcats at 7-5. That would give the MAC six teams with 7 wins for the six contracted slots. Its not possible Miami (they'd be eliminated) and Kent/CMU to win 7 and Ohio isn't getting bumped out of a contracted slot by a 6-6 team.
