OK, but it's not like there's a section on the USMLE that says "by the way, how fast is your fastball? how many 3s can you make in a minute? what's your mile time?". The argument that being an athlete makes it significantly easier to become a doctor is weird, because getting into a good undergraduate institution is not the main hurdle to becoming a doctor.
I don't know about elsewhere but in the UK and Czech Republic, Medicine is a particularly challenging field of study that aggressively weeds out underperformers. You're not making it through unless you actually know what you're doing.
If studying medicine it's easy enough in the USA that the tough part is getting admission (which I doubt) then I think your priority would be to fix your degree courses rather than fiddling with the admissions process. It's still weird to me that you can get into university by throwing the ball good, but if someone can balance what is basically a unpaid professional athletics career and get a decent degree too then more power to them.
