While I would not be in the least surprised that this could be tied to the fake vaccine, this guy is in a high risk bracket for heart attack, and that should be taken into consideration when speculating.
However, it seems so many of these reports seem to be so vague on the cause of death. I know it’s anecdotal to say this but I don’t recall it being quite so prevalent in the past.
Looked for pics but all I found was older ones from when he was still playing. He was a receiver aka thin for a NFL player and could sprint for 100 yards, not a two ton tank of a defensive lineman. Have no idea about his lifestyle post career.
