<p>Ben, I'm not sure what you're trying to prove here. Yes, demonstrated excellence is useful, but a demonstration of tenacity at a sport will probably help you even if you aren't particularly good at it (like me in most sports I've played, ha! :)). You don't have to be a star for athletics, or music, or anything else, for it to count in your favor. It's what it shows about you that really matters.</p>
