How many of you have actually taught college-level individuals who really sacrificed school for sport?

About all I can say is that thank goodness MOST gymnasts don't neglect education to the extent that athletes in some other sports do.
If there's anything sadder in education than trying to teach a 20 year old how to write at a third grade level because the skills have never been taught or have completely atrophied, I don't want to know what it is. Thinking now about my one guy, who had the best work ethic in the world and rewrote his paper five times for me, meeting with me each time to go over the draft and discuss my comments, and how delighted he was when he finally managed to get it over the C- bar. I loved working with that kid because he really wanted to succeed and knew from sports that success demands sacrifice, but I have to say that his parents, his coaches, and his school, whatever it was, all failed him big time. I think gym is somewhat different, but I would not agree that most elite child athletes nowadays, taken as a whole, are ready to succeed in college and that huge span of life that comes afterward.
I worry quite a lot that now, with all of the avenues available to achieve educational standards outside of normal schooling and the American mania for overinvestment in sports, the problem is quickly growing into a crisis that will rock higher education in the very near future. I can't say it loudly and frequently enough: if you are going to go online, do your research and pick a program that is rigorous, synchronous, and not designed simply to achieve elementary or secondary educational credentials for the record books.
There is no cheating, skimping, or skipping on foundational educational skills, any more than in foundational gymnastics skills. If your kid can't read, write, calculate, and think critically and lacks basic knowledge about the world but you expect her/him to succeed in college, you're setting her/him up for a failure equivalent to what one would expect from trying to get a double back out of a kid who can't do a BHS.
Don't let my former student be your kid. Just don't.
