Here's why:
* Academic Standards: Princeton maintains exceptionally high academic standards. They seek students who have demonstrated a capacity for rigorous intellectual work throughout their high school careers. Low grades and test scores indicate a lack of that demonstrated capacity.
* Holistic Review: While Princeton uses a holistic review process considering many factors, academics remain a crucial element. Exceptional athletic ability might help a slightly below-average applicant, but significant deficiencies in grades and test scores are a major hurdle.
* Recruiting vs. Admissions: While coaches might recruit athletes, the admissions committee ultimately makes the decision. Coaches can advocate for a strong candidate, but they can't override the admissions committee's standards.
* The "Overqualified" Pool: Princeton receives applications from thousands of exceptionally qualified students. Even with athletic talent, an applicant with low grades and scores is likely competing against many others who excel in both academics and athletics.
In short, while athletic talent can be a positive factor in a Princeton application, it's highly improbable that it alone can compensate for substantially low grades and test scores. A strong academic record remains essential for admission.
