Here's a few ideas that I think could go a long way as far as gameday experience is concerned.
Someone mentioned this before, and I agree with them. Have the first 2-4 rows across the entire student section is reserved for people with O Zone shirts. Possibly mention in the rap sheet that the these rows will be reserved for people who are wearing this years official O Zone shirt and have it open for everyone else 10-15 minutes before tipoff. I know it'll probably be a little difficult to organize/enforce because that area is so open, but I think it'll go a long way it is enforced throughout the season.
Have someone be a "designated cheer starter" and have others be spread out through the O Zone to encourage these chants. Move them through the dead areas of the student sections to encourage everyone to participate.
1) I really think it should be the entire bleacher section. I'm sure there are more than enough official card-carrying O Zone members to fill those sections four times over, and people can do laundry. Entrance to those sections has been policed by event staff in the past. It's doable. I know there are plenty of casual members that attend games more frequently in conference play. One idea would be to keep the section open to any students in games prior to winter break and then police it in conference games. I'm neither here nor there with that idea.
2) I wouldn't suggest doing anything that might discourage non-"leaders" from starting a chant, but I do think it's a good idea to spread leaders around the sections.
I watched some of the Valpo game online. It seemed as though it was louder than in recent non-conference games. I did notice that when there were dunks or threes from Ohio, some students went straight into the jumping "OHHHH" thing and then they eventually stopped jumping. If those are "leaders", they need to keep going. If they are non-leaders, then something needs to be done to encourage them to make it last the entire possession.
1.) The marketing department (last year and, as they said, this year) are policing the O Zone for member shirts only for conference games. Frankly, I don't have a problem with letting someone get hooked and then getting them to buy the shirt down the line. We will include a notice in the dirt sheets during conference play about wearing the shirts.
2.) We did after our mass meeting last year, only to have 60% of the leaders stop showing up or stop wanting to sit where they volunteered to. Right now we have leaders for three sections, the main group in the middle two sections, and myself and two other students on the farthest section from the 110. For the Valpo game, we were having some numbers problems beforehand, so my section moved to the middle to fill it up. This consolidated the sound, but it could have been louder.
3.) I tried, during the Valpo game, to get something started on almost every possession, and I feel it worked better than normal. I thought it would work kind of like a "capo" in soccer cultures. However, I have some upper respiratory sickness that I am too stubborn to go to a doctor for, so many of the chants actually stopped when I broke down into a coughing fit. There were 3-4 occasions where "OOOOOOOOOOOH" started, and when I started coughing and hacking, stopped. It's a bit of an irk, but we'll find a way through it.
I like it, keep it coming guys!
