I could write a dissertation on this topic. These are only my opinions as a 4-year basketball player at Navy.
I think there are tons of factors that play into this for a SA athlete. D1 sports are no joke in terms of time and intensity. Two items that reign supreme at a SA. You have to really love your sport. The perks are great, team tables, time away from campus, treated like a human for a bit, see the country, miss drill, etc. I think the Brigade is slightly different now in terms of mandatory meals and things, so it might not be as big a difference. All, but one of my room mates was a NARP at USNA. Even to this day they comment how much time my sport took. And one of my room mates was a VGEPer and the other was Brigade Honor Board... in terms of time, wasn't even close.
What many don’t see are the hours and hours spent rehabbing, conditioning, lifting, practice, film, extra practice, road trips, the aching and tired body. During a regular week day of practice in season, basketball was easily 3-6 hours of my day depending on film, training room time, etc. The missed leave. I get that regular Mids are tired too, have a lot going on and tough schedules. It’s not that one is better than the other, it’s we all made our choices and should do what is best for us. It also can vary drastically from sport to sport. Basketball is a very long season (now a distance runner usually runs 3 seasons a year), we play 30+ games a year and it covers all the leave periods except the summer. I missed every Thanksgiving and Christmas Leave period (except 3-4 days) and Spring Break. Summer I usually gave up at least 1 week of leave to work basketball camp. It was my choice to play the sport I did. It is hard to watch everyone leave the yard excited to go home and you are headed to practice. Or walk around the yard on Dec 28th and its cold and dark to your second practice of the day. The other part many don't see are the volunteer activities teams do around Annapolis. Yes, most Mids volunteer and do an amazing job. We spend time with local youth leagues on Saturday afternoons and other things. So many don't realize we do alot of things off the court as we do on the court.
My Plebe Year, our team missed 25 more days of class than any other team on the yard. That wasn't total days missed, that was more. We missed over 50. As someone who struggled academically Plebe year this a tough balance. The football team plays something like 12 games a year. If half are on the road that means 6 road trips with private planes. So they miss 6 Fridays, maybe if they play Thursday they miss a few extra days. I could miss 6 days of class in 2 weeks.
Also, its going from big fish, small pond to small fish, big pond at the D1 level. Everyone is good. For many, putting all that time and effort in to realize you just aren't good enough to crack the travel squad or getting playing time gets old. It becomes a balance of love of the sport, what you get out of the sport compared to what you put into the sport, how impacts you overall daily life at USNA. This is one of the reasons I always say I don't care why someone came to USNA, but why they stayed. Very few quit their sport and leave USNA. They become NARPs or join a club team and channel their efforts elsewhere. There are tons and tons of former athletes in the Brigade.
In the end it comes down to a very personal decision. For me, the structure and outlet it provided were very positive for me. The time management it taught me has served me well in life. Would I have been a better student if I did not play, pretty sure I would have. But, the leadership lessons and memories, I wouldn't trade those for anything. In the end I think it made me a better Mid and officer. Everyone has to do what is best for them.
