Yes, it is actually a very dangerous sport because it's played by fragile old people who are out of shape or struggling to stay in shape play it and so it's easy for them to just like fall and receive irreparable injuries or simply dislodge blood clots from the exertion leading to a heart attack or stroke.
What even is the conspiracy angle, that the Mossad wanted to whack a geriatric scammer who's exploited and endangered countless teenage girls? Like I'd think if that guy were to be assassinated it would have been some aggrieved dad out for revenge over his daughter dying/being crippled/getting abused in the programs that guy founded and he would have just walked up and started blasting in a big loud show of dominance and rage that affirms his ego.

Get a young guy with a really strong serve and just let him work.
