In ALL athletes - not college athletes - may be due to myocarditis. I assume that those were flu or related myocarditis infections.

So how many college athletes die sudden heart failure every year? One? Two? What is 9% of that? Is that even statistically significant? Is there a number out there?

9% could literally be 1 out of 11 in the last ten years. Your 22% might be 2 out of 11. We don’t know.

The article seems to build a case that myocarditis is old, usually nothing, and throughout history, has killed a very small number of people.

I’m looking for a reason to believe this threat is significant.
