Vid,
Im sure you have heard the term,'correlation is not causation'.
Since 2000, in Australia, about 1 person has died every week playing organised sport. Guess what the leading cause of death is? Cardiac arrest. Just like now.
Ive seen other posts like yours with claims of sports deaths related to the covid vaccine. As soon as you start drilling into the figures, there is no proof of anything to do with covid. Some of these lists even include heat-stroke and suicide, just to pad out the numbers no doubt.
