Maybe if you would read you'd be able to answer your own questions.
1) This is DIY AF because the data isn't being compiled elsewhere.
2) Every single event they track in the chart is listed below if you scroll. Every report and news story covering each of the 400+ incidences. So it looks like they're "showing their work".
3) The key issue is most international soccer clubs won't state the vaccination status of any player, despite vaccine mandates for most clubs (and European countries). So maybe these don't have anything to do with the vaccines. If you believe that I have some nice oceanfront property to sell you in AZ.
All of this is stated by the authors, if you'd read anything.
And I've said 100 times why I don't think the medical community is speaking out - or at least the mainstream isn't. There's plenty of doctors who've spoken out and paid the price.
1) The FDA and CDC establish the narrative and protocols.
2) State medical boards answer to these governing bodies.
3) Therefore any doctor or nurse who speaks out has to either do it anonymously or face severe repercussions - such as losing their license. These are people with families to support that worked very hard to achieve their station in life.
4) The absolute value of the numbers is very small. They are only meaningful when you do some trend analysis. But remember, "rare" is only rare if it doesn't happen to you and I'm most interested in understanding the effect of a change in variables (i.e. the introduction of the vaccines).
5) Causality is really difficult. Even in my own world, my wife's doctor isn't sure if the vax caused her issue, as an example. Best she could say is "we can't rule it out". That's the issue with an experimental medical technology in a system as complex as the human body. We may not know for sure the full impact for many years.
Here's another article from Israel that cites more than one study. The conclusions are the same - we're seeing a massive uptick in healthy athletes with heart injuries or death.

All I see from you is denial and attacking of sources. So why don't you do some research. Show the board that there's no increase in serious cardiac outcomes from these vaccines. And use evidence, not fact checkers. Pfizer and Reuters/Thompson have the same corporate governance, but I'm sure you were aware of that conflict of interest.
Maybe I can get you to be a little more open minded by asking two questions:
1) Have the vaccine manufacturers admitted to increased incidence of myocarditis and pericarditis in young men (specifically Pfizer)?
2) Can extreme exercise with those conditions left untreated lead to serious heart problems?
