So I think there are some significant pros to being a three-sport athlete–but college admissions is not one of them.
The pros in my mind are things like: potentially making more friends; cross-training, which is good for general fitness and reduces the chance of injuries; having more recreational options in the future, including college; and developing a generally sustainable vision of the role of athletics and fitness in a well-balanced life.
When it comes to college admissions, I do think the three-sport varsity athlete with a captainship or two is a known type, and it is specifically known that is a big time commitment through the year, which requires good time management skills to balance with academic excellence. So in that sense it is a good answer to the question, “What have you done besides classes?”
But it is only one possible answer. Like, if you replace one of those sports seasons with a debate season, I don’t think that is going to be an issue at all.
OK, but what if you replace not one season with debate, but two seasons with club? And maybe even more than that if you also devote most of your summers to your sport?
Part of the answer is obviously that path may realistically be your only chance to be recruited. I do think if a kid is only doing it to get recruited, that is likely a mistake. But if the kid truly loves the sport, AND would love to continue it in college, AND that means being recruited is possible, then that is fine.
Still, I think it is OK to have questions. Like, is so much focus on one sport a greater injury risk? Is the kid maintaining a healthy and sustainable balance between developing in their sport and other important parts of childhood development–social, intellectual, ethical, and so on? If the kid ends up not recruited, or not by a college they want to attend, or an injury ends their competitive career, or so on, will they still be happy with how they spent their time? With where they went to college?
These are real questions, not rhetorical questions. If a kid can focus on one sport and still answer these questions in a positive way, then I think college admissions will work out fine, because colleges will again know what time commitments were involved, know the time management that was required, value being able to balance all that with academic success, and so on.
But sure, go ahead and ask the questions. And be open to them having satisfactory answers.
But the question I would not ask is, “Would it be better for college admissions if my kid was a three-sport athlete?” I don’t think so, and I also personally think those hypotheticals are not worth asking anyway.
