Playing NFL quarterback is stressful. There's a lot you need to think about before each play.
Yet, lining up under center should be pretty automatic when you've played the position for a couple decades.
Kirk Cousins had an embarrassing moment and it couldn't have come at a much worse time. The Minnesota Vikings trailed 34-26 against the San Francisco 49ers. In the fourth quarter they drove inside the 10, then went for it on fourth-and-goal.
Cousins was getting everyone aligned properly, but forgot to do so himself.
