The No. 4 MAC bowl team is supposed to go to either the BBVA Compass Bowl (Birmingham, Ala., Jan. 5), New Mexico Bowl (Dec. 15) or the Beef O'Brady St. Petersburg Bowl (Dec. 21) if any of those bowls cannot fill their obligations. I'm not sure really sure which bowl gets the MAC if more than one of them does not meet its standard. Last year it was the New Mexico Bowl taking Temple.
The No. 5 MAC team is supposed to play in the Ticket City Bowl in Dallas (Jan. 1) if it cannot fill its slot (which seems extremely likley considering one of the teams is supposed to be from the Big Ten). Last year, the No. 5 MAC was supposed to take part in the Kraft Fight Hunger Bowl (San Francisco) if needed, but that bowl actually was able to fill its spots with its regular tie-ins.
After that, the MAC would fill in wherever a spot is open. The Military Bowl (D.C., Dec. 27) has been one that has had an opening that went to a MAC team two out of the past three years. Army is slotted for it this year, so there will be at least one opening there, but the MAC has no contract to take part in the bowl in any way. There are a number of other bowls that undoubtedly will have openings.
I think the MAC will get at least six bowl slots this year. It's still conceivable an eligible MAC team gets left out. Even having lost to Miami, Ohio will get picked ahead of Miami. The RedHawks will be lucky to become bowl eligible. They need to win two of three against Kent State, CMU and Ball State. Western Michigan could become bowl eligible by beating EMU and Buffalo. Central Michigan would have to beat EMU, Miami and UMass to get to 6-6. In the event these teams do get eligible, they'd have a legit shot of going to a bowl because there will be barely enough eligible teams to fill all the slots.
