Here is a great article on Rivals by Chris Balas about what it is to be a 'Michigan Man' and how it is defined. I find it great to see how other people outside of Michigan look at the love, dedication, and pride this great university instills in its' Alumni. Sorry if this article is paywalled, but if you have access it is a great read. GO BLUE!
FWIW. Michigan doesn't seem inclined to get re-involved.
