The [University of Michigan athletic] department has run ads on its blog, its electronic billboard, on TV and even at a street stand during the Ann Arbor art fair, urging fans to buy football tickets. If those unprecedented efforts didn’t tell us how eager they must be to unload tickets by the thousands, the email this week to its golf club members, announcing free tickets for anyone who asks, removed any doubt. If you went to Michigan, live in Michigan or can find Michigan on a map, don’t be surprised when the athletic department offers you free Michigan football tickets. It’s a boon for those who’ve already dropped their tickets – and a bust for those who have already paid full price for theirs.
