It is hard to even get an estimate of UM football season ticket holders. It sticks in my mind that I read on this Board ahile ago that the number for this season was less than 20,000. If I wasn't dreaming that, I have no idea how that poster arrived at that number.
A number of years ago UM basketball announced a complete season sellout for the Watsco Arena on campus. That's around 9200 seats.
Yet, with one or two exceptions, the place was never more than half full, often less. Again, for a game where they had maybe 4,000 people actually in the stands, it was hard to believe that 5,000+ would simply have chosen (despite having already paid for tickets) to stay home. That, again, is an awfully high percentage of no-shows. Makes you wonder.
