You may be able to walk on - you may not.
If you got into Brown and did not make the team, would you still be happy?
There are research opportunities at most every school - but if you want an open curriculum, are you also looking at Rochester, Vassar, and others that have this option - even Kalamazoo?
Some jobs seek athletes - it shows teamwork, time management and more. Many sales jobs like the “outgoing” aspects of performing. But in life, you’ll find non athletes that are very successful. And athletes that aren’t.
ON the flipside, being an athlete will offer you less time to do other things.
In the end, you’re going to have to make the decision for yourself as to where to apply and who to prioritize.
Best of luck.
