It would have been possible for the Green Bay Packers to pack up camp and go play golf.
When the fourth quarter of Sunday's game began, the team was already behind by two touchdowns and had lost five straight games.
However, Green Bay didn't give up.
They ended up surprising the Dallas Cowboys 31–28 in overtime.
After a win that preserved their season, coach Matt LaFleur was overcome with emotion.
It's not simple to maintain optimism and vigor.
