I think as seasoned football fans you're used to certain scripts playing out. The scene we've seen so many times of the player being immobilized as the players of both teams kneel in prayer. then the cart leaves the field and often the injured player gives a thumbs up to show he has movement. The crowd cheers and the players feel they can continue knowing their guy has some movement at least.
Last night I was expecting to see the same scene, then they showed Josh with that look of horror mixed with worry mixed with shock, plus the tears in the eyes. Then they showed Diggs and White in tears. That was such a powerful image and something I haven't seen before that it really hit me.
Finally those words from Buck about them administering CPR. That was so surreal and was the moment when I was thinking "Jesus, this young man is literally dying in front of his teammates".
The whole thing was just so surreal and disturbing, not just for Bills fans but for anyone watching. It's amazing how you can go from being so pumped about the game and so rabid about every mistake or big play your team makes out there to literally not giving a damn about plays or scores or standings
