Application Theme: How to make it flow?

<p>Okay, I think I'm getting this 'application theme' thing down. (Hopefully.) My ECs pretty much split into two groups: Statistics/Actuarial Science (my future career) and sports.</p>

<p>Unfortunately, none of my volunteer work has much to do with either of the two. (There's not too much there either, just tutoring and mentoring.)</p>

<p>How should I inject these two themes together and into my essays and application? Ideas include: statistics of playing fantasy football with family (2 seasons), informal challenges/contests during Calculus (and everywhere else) last year, or any more suggestions? I know I have many experiences, I just can't find which ones convey my two main EC categories and are unique.</p>
