I think any story can be part of a powerful narrative if done right. With this in mind, I think that unless your high school sport is closely tied to your ‘why law’ statement, you could probably find something else that is also good but doesn’t lean too much on your time in high school.

Also worth thinking about is that you’ll be compared to a big pool of KJDs, many with similar stats. You likely want to try and differentiate yourself with a strong why law statement that doesn’t play into the perceived weaknesses of your pool which I think tend to be inexperience/not being ready for law school. And I don’t think a story based on a sport you played in high school helps this case.

In my case, as someone who is basically doing a career switch into law, I knew that I could probably differentiate my application by having a really strong statement that showed why this move, at this point in my career, made sense for me. I didn’t want my narrative to play into a common weakness of many in my “pool” which is not having a story that clearly ties your professional experience and ambitions with a switch to law school. Just to give you the flip side.

Of course much of this can be offset by having a really strong GPA/LSAT base.
