McCarthy wasn't kidding.
Along the way, Atlanta's 30 first downs fell just four short of an NFL postseason record. Had the Falcons cared about such a mark, they could have reached it with ease. A 24-0 halftime lead for Atlanta also marked the first time Green Bay had trailed by 24-plus points at the break since the beginning of the Aaron Rodgers era in 2008.
"We didn't stop them at all, defensively ... Their production (in first half) was a big key," McCarthy said.
"We needed to keep pace with those guys ... There were communication issues. There were a handful of times we couldn't get a play in, and that's a credit to the crowd."
The Packers couldn't "keep pace" with Kyle Shanahan's fascinating, electric offense -- and they couldn't get out of their own way with a missed field goal and game-changing fumble over their first two drives. The turnover triggered a 14-point swing as Atlanta raced right down the field for another touchdown and the 17-0 lead.
Running out of ways to describe Sunday's bloodbath, McCarthy conceded: "They played lights out."
It's the kind of loss that allows for plenty of finger-pointing. The defense imploded and the Rodgers-led offense fell to pieces, while Green Bay's typically sturdy offensive line allowed a pair of sacks and seven quarterback hits.
After looking like Super Bowl-material a week ago, the Packers on Sunday were reduced to a footnote along Atlanta's path of destruction through the NFC. Any questions about the better team were put to bed with force.
Said McCarthy: "Frankly, we ran out of gas."
