RizzleDrizzle - it's healthier to stop speculating. Really - especially on a thread where people are distressed about seeing their options slip away.
The sport? Unless you're really good at it - Varsity level - it's not going to make much difference at this point if you apply for the next year. You won't have had much of a track record to go on.
Just be yourself, stop looking for the right "hook" to attract a school. There are few and those change each year depending on who is in the student pool. The people I've seen most disappointed are those who live their lives calibrated to what they think will get them in (and then don't). The students who are most successful are those who live their lives doing what they have a passion for despite the outcomes. And even in the latter case there just isn't enough space for everyone who wants a spot.
So yes - take the sport if you really love it - but recognize there will be a lot of other students in the application pool with the same sport on their resume.
