To continue the issue of Michigan home and away under Hoke....
If you compare end of season (or current for this year) rankings, you'll see M plays teams close to their ranking, as you'd expect. Wins at home, loses on the road (thus the term "home field advantage").
I only see two games that clearly doesn't follow that formula since Hoke has arrived (using CFRC rankings):
-Road 2011 Iowa #44, M#11.
You may count PSU this year, as well (CFRC PSU #48, M #34), but as you get this far down in the rankings, the teams are more of a jumble. By the end of the year, the rankings will likely be more similar and it will be more clear that this isn't a road upset. .
At home, M (CFRC #34) beating ND this year (CFRC #24) is the only time Hoke has beaten a team that is higher ranked than M.
So, only 2 (or 3) games in his 2 1/2 seasons truly go along with the theme we keep hearing.
