I guarantee you almost everyone on that field personally knew Thurmon. Many of them had been teammates of his. So why is the shock of his death any less? I assure you there were people there that did not feel the same after the news.
You name a few occasions where a tournament or game was cancelled due to a tragedy. The 1993 Citizen's Cup in Hamburg continued on after Monica Seles got stabbed on the court by a fan. It was extremely shocking to all that witnessed that. Obviously she didn't continue, but the tournament wasn't automatically cancelled.
I just don't get folks like you with such strong fascist level opinions that you want to virtue signal how much more caring you are than the rest of us realistic scum.
The fact is the guy did not die, and even if he did there was not a danger to anyone else on that field. The game, as life, goes on.
