The bigger prize fund wouldn't change the fundamental problems with the PBA. Bowling as a sport has decline so much that the number of people who watch the PBA aren't enough to attract big dollar sponsors. This money would just be flushing money down the toilet. Yeah, the pro's might have a few more bucks in their pocket, but the problems and lack of viewership would still exist.
Now take those 3 bucks, and give 100% of it back to local associations for the strict purpose of developing, and building strong youth leagues to rebuild a weak base, would be the way to go. To save bowling the sport, we must get kids and teens to think bowling leagues are cool, and worth the time investment over playstation, and all the other entertainment options available to them. Generate a greater interest amoung kids, would lead to greater viewship of the PBA, and sponsors willing to pony up the dough. The ABC, USBC, and PBA have all dropped the ball and failed to focus on the youth, with has resulted in several generations with little competative interest in bowling.
