You may not agree with all or any of these, but I've compiled this list from the last 10 years I've spent in this sport from what I've heard from coaches, wrestlers, refs, fans, and boosters, and the time I've spent in other states with wrestling and other sports:
1. Don't gouge the fans at the gate - JCTC was $13 for both days this year for one adult. Last year it was $7 for a 2 day pass. I heard several people calling their significant other this year and telling them not to come because it was so expensive. High ticket prices only supports the sport at one school, not the sport as a whole! Keep it reasonable for a one or two day event. $10 or less for a 2 day pass is reasonable for most tournaments. Make it up in concessions and t-shirt sales.
2. No cooler fees for teams - If a team chooses to pack drinks in a cooler, why charge them? So you can compensate for what you lost at the concession stand? I saw a team this year start packing drinks in their gym bags when they heard there was a cooler fee. If you're concerned about what you lose, add $10 to the team entry fee. At least the school is paying for it then, as opposed to a coach at the gate.
3. Make sure your concession stand is stocked - I can't tell you how many times I've been to tournaments where they run out of drinks, food, etc. Bad experience for fans and wrestlers.
4. Allow re-entry without buying another ticket - I don't see this much, but when I do it pisses me off. Wrestling tournaments don't last 2 hours, they're AT LEAST a 5-6 hour affair. If someone buys a ticket, they're paid. This is a pitiful way to make money.
5. Keep down-time to a minimum and stay on schedule - I won't get into the seeding in advance, that only makes sense. But, keep the tournament running, mats full, and eliminate the long process of deciding the champs. Tell me why JCTC ended at 5:00 p.m. on Saturday in 2011 and 9:00 p.m. this year.
6. Recruit workers - don't hold a tournament if you don't have the people to help. Usually this is seen at the scorers tables.
