Harry Plumer at MASSLive.com has been doing a great job covering the MAC. He has a daily MAC Lunch Links post that's pretty good.

Here's a piece from Friday's post on Las Vegas odds of winning the MAC Championship:
The odds are in moneyline format — so when you see Ohio (+140), that means for every $100 you bet, you would win $140.
MAC EAST:
Ohio (+140)
Miami (Ohio) (+360)
Bowling Green (+360)
Kent State (+400)
Buffalo (+900)
Akron (+1300)
MAC WEST:
Western Michigan (+180)
Northern Illinois (+260)
Toledo (+315)
Eastern Michigan (+650)
