Someone who understands the tradition and styles of Michigan Football as a culture. He does not have to graduate from the school (see Bo Schembechler) or be from the state of Michigan (see Charles Woodson). All that one needs to do to be a Michigan Man, is understand the tradition of Michigan Football and to try to continue it, placing it about all else.
Even though Brady Hoke is from Ohio and went to Ball St, he is a Michigan Man. This is because he cut his teeth being an assistant coach at Michigan and helped them win a national championship in 1997.
