Here's my view on varsity athletics...They might help you have something to talk about in an interview, but golf is going to be fairly unlikey to be something that people consider amazing. The sports that I see (and from my conversations w/ other interviewers) to be likely to have a big influence while maintaining high academic achievement are: Football, Wrestling, Basketball & Soccer to some extent.
All the sports I listed have fairly long seasons & require a great amount (especially football & wrestling) of outside of practice time. Don't get me wrong, I love golf. However, when I wrestled collegiately, not only did we have 3+ hour practices, but we had morning & evening runs/weight lifting too. Atheletics are a great conversation piece, but they may or may not have any influence on your final decision.
