A good bowling resume never hurts, but it is more about sales and visibility. If they think you can move product, you have a shot. They want people who are affiliated with pro shops, who bowl lots of events (leagues, tourneys, etc.), and who are good at getting people to notice their products. Again, this isn't to say that staffers aren't normally good bowlers; they usually are. However, you'll also see plenty of staffers who have deals based upon sales, not bowling prowess.
