For those wondering:

We should all continue to pray for the recovery of Damar Hamlin. He seems like a good young man just beginning his life.
When tragic events happen we need to take a knee for a moment: pray, pay our respects, check on those injured, and continue to take life one day at a time treasuring every moment because things could change in an instant.

With this in mind, I see no reason to replay the game if the outcome will not affect the playoffs. They should agree to a tie game or no game.
For Fantasy games: If the game is not played, then they should use this weeks scores for the Mon night game for players on the Bills and Bengals. This weeks scores would also count for this week and the Monday game or take the average score of the season for each of these players.
If the game is made up, then use those scores for the make up game.
This is a good time to reflect on how delicate life is. Let go of any anger towards anyone or any group. It solves nothing. It heals no one, and it destroys joy. Since life can change in an instant we should not waste it pondering that which causes us anger. Instead, focus on what brings us happiness and joy and let others handle those things that cause anger to stir within us.
Smile more. Laugh more. Visit others more. Talk lovingly more. Say thanks more, especially to those who serve you at the grocery store, restaurants, or anywhere. Let others know you see how helpful they are, how gifted they are, how wonderful they are.
May God be with Damar Hamlin who brought joy to many who were able to watch him on the football field.
