People keep saying this sort of thing, but it's just not true. When we were winning under Royce, the place still had tons of empty seats... I know, I was there damn near every home game. The bottom line is there are a ton of entertainment options, even in little ole Terre Haute, that Sycamore athletics have to compete with.
If you look at consumer loyalty, I'd say incentive programs have been a big part of that. I pretty much buy gas exclusively at Speedway because of their points program. Hell, I've passed 3-4 gas stations needing gas to find the Speedway so I could get my points because I know I'll get to take my family out for a free dinner twice a year on them.
The worst thing they could do is try to have an incentive program and it fail. The best case scenario is they get a new segment of fans into the door and get them hooked. Additionally, I'd imagine you could do something like this on the cheap if they have someone that can land some sponsors -- I'd imagine Wal-Mart would have no problem donating some video game systems and iPods to have their name in programs, on signage and mentioned at the game.
