I mean I started that first comment with "It is anecdotal". I realize this isn't hard science, but pretending that it is meaningless because it "is not impossible" that he had a prior condition is also pretty worthless from a scientific standpoint. I don't think you realize how closely professional athletes are monitored nowadays. We obviously can't say anything with certainty while observing from afar, but it is incredibly unlikely his condition wasn't caused by COVID. And since this is just an anecdote, I don't understand the inclination to advocate for the devil and that tiny likelihood of it not being COVID related.
