Again, just playing devil's advocate, I would never put hard-won money on either team.
But I'm guessing if last week's Eastern Michigan line was -7 for a home game vs. a Division II team that was 0-2 coming in against other Division II teams, you'd think EMU would be an easy cover. They lost. Can't imagine Eastern Illinois is that much better than Idaho, if they are at all. I just know Idaho has played some extremely stiff competition and may see this as their best opportunity at a win, whereas Eastern Michigan already knows it can lose at home to Division II types.
Good luck...It will be fascinating to see how this one turns out.
