First of all, don't be tempted to think that football fundraising ideas you have done in the past should automatically be discarded in the "done that already" pile. In fact, many schools do the same football fundraising every single year. Why? For the simple reason of not messing with a formula that works. If you have found a football fundraising activity that consistently performs well for your team, then that's an indication that people like and enjoy what you're doing, and it makes sense to stick with that rather than trying something else just for the sake of it. You you really do want to branch out into other areas of football fundraising, try running a new fundraising idea alongside the old one, and see how well the new one works out. If you find that your new football fundraisers works well, great. But if it turns out that the new ideas doesn't do quite as well as the old favorite, then at least you can say you tried, without sacrificing any of the income that your old football fundraising technique brings in.
Schools love traditions, and football fundraising traditions are no exception. Many times people get excited about your football fundraising specifically because they remember it from previous years, and they look forward to something that only comes around every once in a while, a football fundraising effort they can get excited about and rely on being there year after year.
