I may be silly, but I just don't understand why it's so hard to balance the two. I was very good friends with a Division I student athlete throughout college, and she managed just fine. I also have a cousin who was a D1 gymnast who had to train all year with her team and graduated in 5 years. If one takes 15 credits, that means that -- in theory, they could have a class on M-W-F at 8, 9, and 10, and then two classes on T-Th at 8 and 9:30. They could be done before noon, train until 5, then have several hours to study (plus weekends). Someone here is going to tell me all of the reasons why this doesn't work, but I honestly think that it doesn't work because the athlete starts living the college life on top of the training and studying.Just my two cents...
As somebody who worked full-time once I got back into going to college full-time until my senior year of college while going to college, it's hard and you can be really exhausted to fully excel. Often times classes one needs to take won't be on a M-W-F schedule in the morning. They can stagger based on availability. Also, as much as I joke about how much easier college was than law school, when I actually remember how busy I was with the course load in college, it actually was a lot. It's not just going to class and studying a bit a night and the weekend, often times, you have very involved tasks, research, labs, papers, projects, etc. on top of studying for quizzes, tests, mid-terms, final exams, etc. In law school, we're not allowed to work more than I think 20 hours a week unless you were a part-time student because they know you're supposed to spend all that outside classroom time reading the material and studying, working on legal research and writing assignments, and truly getting it before every class and unlike college, we didn't have quizzes, tests, or mid-terms...just a final exam at the end that our entire grade is based on...of course you better be prepared before every class because the Socratic Method is going to get you.
Also, collegiate sports are made with an academic schedule in mind and are worked around it and the training bases are on campus. NCAA also has strict rules about how many hours an athlete can spend practicing and training unlike elite figure skating where skaters say they train about 7-8 hours a day on average (including on-ice and off-ice training) for 5-6 consecutive days. Some universities will be willing to work with elite athletes and form some sort of part-time schedule and we know skaters have been able to juggle both. However, Yale doesn't seem to be the type of institution that would work around an elite level athlete's schedule.
As much as we find Nathan amazing, Yale has tons of amazing people that they expect to graduate within 4 years taking the full-course load. Plus, Nathan is competing in the Mens event where he's trying to do 5-6 quads a long program and 2 quads in a SP in order to stay on top. It's a much more time-consuming and physically-intensive type of training than collegiate sports. That and trying to do a full-course load at Yale (especially if one is going the pre-med route) is really difficult and will be exhausting that many people can't see how he can exceed in both if tries to do both full-time.
You used gymnastics as an example, as much as I make fun of the lack of depth internationally-speaking, the level of skills elite gymnasts do across 4 (women) and 6 (mens) apparatuses for the most part far exceeds that of a college gymnast. That's why some elite gymnasts cannot do all events on the elite level and must specialize on 2-3.
