You know what you call a doctor who got C's? A doctor.
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.
