I understand why Bills fans don't want to understand why it's not a catch. They're emotional and invested. It's natural. They're quite literally coping.
I genuinely don't understand how anyone who is not a Bills fan does not understand that Cooks didn't survive the ground. It does not matter that for a fraction of a second his knee is down, and he was touched. That's not the rule. The moment he hit the ground, he lost control, and the ball wound up in McMillian's arms.
