It's a difficult thing, and there really is no right or wrong answer, but I think you have to keep moving forward.
My thoughts and prayers are literally with the young man and his family, and stopping that game from moving forward this week is the absolute right thing. But the game has been dangerous for 100 years and will be for 100 years. I know it's a horribly traumatic event, but not playing games this week doesn't accomplish anything big picture or change that. It's going to be as dangerous 2 weeks from now as it was last night. If anything, it brings attention back to the topic and discussion of safety and his life/mission/healing.
Obviously there is the other angle that you want players, coaches, fans, etc to take time to process everything, but that should be done in other ways as well - counseling options, education, discussions, etc. If the players or coaches asked for the time, then sure I fully support people needing that. But if they didn't or don't collectively ask for a full week delay to the schedule, then that's different.
I don't know, it's hard to say because there is no right or wrong. As a society we've set precedence with horrible events moving out of view too quickly and expecting things to go back to normal and I guess I don't see why this would be different if that's the way we do it. I don't support it on those other things (school shootings, stabbings on NYE in NYC, etc) but it's been that way so I have a hard time treating this differently.
