Here's an update for the stats nerd folks from last weekend...
----EYES ON NOTRE DAME:
In the all-time winning percentage race with Notre Dame, Michigan maintains a .0019 edge, .7305 to .7286 (or about 2.5 games; a loss for either of these schools lowers its percentage by about .0006; a win raises its percentage by about .0002).
Michigan of course maintains its 39-game margin in the wins race, 936 to 897.
----LAST WEEK, WHEN RANKED BY THE AP:
Michigan plays in a game involving two AP-ranked teams only a few times a year, so last weekend's game (#11 vs. #17) was notable for that reason.
In the era of modern Michigan football (since Bo arrived in 1969):
Michigan is 22-4-0 (.846) when playing as the AP #11, one of Michigan's most fruitful rankings from the standpoint of winning percentage. Last loss: October 15, 2011, at Michigan State 28-14.
Michigan is 9-1-1 (.864) when playing against the AP #17, which is Michigan's best percentage against any place in the rankings. Last loss: October 9, 2010, Michigan State 34-17.
Michigan is 365-111-7 (.762) when playing as an AP-ranked team.
Michigan is 55-41-1 (.572) when playing a lower-ranked (but not unranked) team.
Michigan has moved up to AP #8 for the game against Cincinnati.
Since 1969 Michigan is 18-6-0 (.750) playing as the AP #8. Last win: September 4, 2004, Miami (Ohio) 43-10. Last loss: September 1, 2012, Alabama (in Dallas) 41-14.
