Rob Gronkowski donated $6,900 LOL he is a clown.
Not everything is knowable. Go watch the press conference with the DR's they explained commotio cordis is diagnosed by ruling everything else out. Not sure we know everything has been ruled out but people seem to be assuming that. There is always a chance there is something new/unique. In any event, he has DR's to guide him making the right choices in the future, not this forum, haha.
