Probably half of them had to sit out games because at times they were sick. And then there is the obvious fact that if myocarditis is even more prevalent now, it is because the virus itself causes it, which is why the vaccine can also cause it, because like most people who bothered to do due diligence would have worked out, even the flu causes myocarditis, so the difference between the last 2 years and the previous 20 is that there was a much more contagious virus going around than usual.
Seriously, this is all elementary stuff if you aren't getting your facts od the footy show or right wing twitter feeds
