GREEN BAY, Wis. — It was the perfect, disastrous letdown to illustrate the first seven games of this season, or really, the past two decades of Washington Football Team seasons. Taylor Heinicke, a quarterback who grew up loving the Green Bay Packers, thought he had scored a touchdown late in the third quarter. He spotted a fan in a white No. 17 Terry McLaurin replica jersey and decided to go for it: a playful Lambeau leap. A lifelong dream fulfilled, even though it came as a foe.
