I am not disagreeing with anything you say, but allow me to present a counter-balancing view.
First, make this a UM production. Don't let some secret-Gaytor-fan cameraman working for Sunshine take several opportunities to pan around a near-empty stadium. We get it, we are not some SEC program in an area of the country that gets some snow. Yes, this is not the first chance for SEC fans to come out of their hibernation and get some sunshine on their lily-white skin. Give the film students of UM a chance to work behind the cameras to film the action, not the empty seats.
Second, combat the "mom-and-pop" reputation (fair or not) by acting like the "big boys" act. Treat this as an event. Market this as an event, even if the first few years do not result in a huge bump in attendance. Take advantage of the parking lots, set up volleyball courts, make it a big "beach party" event that is free to the public. Make it an all-day event (outside the stadium). Give tours of the stadium. ****, give tours of the locker rooms, etc. There are parts of the stadium that an "everyday Joe" will likely never see. Seriously, as a guy who once worked for NASCAR, I can tell you first-hand how much young kids love it when they get to see all of these cool things they never get to see, when they get to meet the athletes, when they get to tell their friends what they did over the weekend.
Third, make the video available on every platform possible. Heck, put it on MySpace, I don't care, as long as everyone who wants to see it can see it. Even broadcast the footage of what people are doing outside the stadium. Clempson can have their slide, we've actually got real people of many different cultures all enjoying a day in the sun and bonding over UM football. Remember how that Delta Gamma sorority rush video went viral and made everyone outside of South Florida wish that they could go to UM? Do the same thing with UM football.
I'm just tired of some people who respond with the "show up for the Spring Game in person or else don't complain" mentality.
