This doesn't just apply to sports. Most people don't share my enthusiasm for math and science but most people are enthusiastic about something. I enjoy asking people what they do for fun, or about an interesting (to them) project they may be working on. Almost any topic can be interesting when explained by someone with the right passion. Even if I don't especially care about a given topic it's not too much work to appreciate why someone else might, which is a good way to avoid being a snobbish jerk.
