Time to run these again.
Needless to say, this past weekend wasn't kind to Michigan on this front, as Nebraska dodged a bullet and except for Penn State the teams they'll face the rest of the way posted poor results.
The usual caveats apply--this assumes the probabilites are independent for each game, and while that becomes a better approximation as each week goes by it's completely ignoring (among other things) the possibility of a significant injury to a key player. That increases the likelihood of an extreme result and means the division-winning chances for the less likely teams are a little better than they appear here.
Massey win probabilities for the remainder of the season:
Michigan:
- Northwestern 64%
- Iowa 80%
- Ohio State 36%
Nebraska:
- Penn State 67%
- Minnesota 92%
- Iowa 77%
Northwestern:
- Michigan 36%
- Michigan State 44%
- Illinois 95%
That works out to:
Michigan:
- 3-0 18%
- 2-1 48%
- 1-2 29%
- 0-3 5%
Nebraska
- 3-0 47%
- 2-1 42%
- 1-2 10%
- 0-3 1%
Northwestern
- 3-0 15%
- 2-1 47%
- 1-2 36%
- 0-3 2%
Chances of winning the division are now 85% Nebraska, 13% Michigan, 2% Northwestern.
There are some bizarre possibilities still out there, like a 5-way tie at 4-4 (either Minnesota or MSU has to lose at least 5, since they still have to play each other). None of those possibilities let Minnesota or MSU win the division; they would always lose the divisional-record tiebreaker.
On the leaders side it's:
Wisconsin:
- Indiana 70%
- Ohio State 46%
- Penn State 51%
Indiana:
- Wisconsin 30%
- Penn State 27%
- Purdue 60%
Odds of winning the division are 77% Wisconsin, 23% Indiana.
Everyone else has been eliminated. There's still a possibility of a 3-way tie if Wisconsin loses out, Indiana loses both non-Wisconsin games, and Purdue or Illinois wins out. If it's Illinois they'll have lost to the other two and Indiana's win over Wisconsin gives them the tiebreaker and a trip to the championship game as a 5-7 team. If it's Purdue, the three teams will have split with each other, Indiana will be ruled out because they'll have the worst record in the division, and Wisconsin will then win the tiebreaker thanks to their win over Purdue.


I love our defense. If our offense produces at all like they did last year I like our chances of beating Ohio. I'm more worried about this week for some reason.
There is god, there is family, and then there is MICHIGAN FOOTBALL
