Wiki on NYGs vs Packers in 2011
"Eli Manning threw three touchdowns, which proved to be instrumental in the Giants victory, thus dethroning the Packers from their World Championship as their overall record stumbled to 15–2.
The Packers recorded a season high nine dropped passes. They also recorded a season high four turnovers in the game. The coaching staff of the Packers, in particular head coach Mike McCarthy waved off the Packers precise practice performance in the week leading up to the playoff game. The reason for the inefficient offensive performance from one of the league's most historically prolific offensive units is unknown, though the Packers' decision to rest their starters may have been costly to their players, as doing so tends to put players "out of rhythm". ..Quarterback Aaron Rodgers went a full three weeks without taking the field, and the offense dropped several crucial passes. The Packers also became the 3rd team to finish the regular season 15–1 and not reach the Super Bowl, and the first to not win a single playoff game."
