I can only speak to my era...a LONG time before you were born!
It's not "unheard of" or "impossible" but it's not easy. There are quite a number of outstanding athletes recruited to USAFA that are also amazing academicians!
Truth time...I spent 4 years walking the terrazzo constantly asking myself: "HOW did I get here with THESE people?"
I "walked on" and made the track team. But academics ended my athletic career after 2 years. I applaud/stand in awe of those athletes that can compete successfully in Division 1 athletics at USAFA and do well academically!
