The lesson? Just hold onto the ball.
Each team gave it away four times. Each team returned a fumble for a touchdown M.D. Jennings ran one back for Green Bay (1-2). The Bengals blew a 14-point lead, and the Packers let a 16-point lead get away in the second half. Green Bay scored 30 consecutive points and lost.
The Bengals were the first team in NFL history to lead by 14 points, then trail by 16 points and rally to win, according to STATS.
And no, the weather wasn't a factor. Nobody could blame the cool, sunny afternoon for all the oddities.
"There's been a lot of crazy games since I've been here," seventh-year cornerback Leon Hall said. "But that one's up there. Top three."
The Bengals (2-1) finished it off when Michael Johnson batted down Aaron Rodgers' fourth-down pass at the Cincinnati 20-yard line with 1:21 left, ending a subpar showing for the quarterback.
It was the first time in 14 years that a team won after allowing an opponent to score 30 consecutive points in a game.
"We didn't flinch," safety Reggie Nelson said. "You expect a great team like that to score."
The defense made the difference against Rodgers and Green Bay's high-powered but injury-depleted offense. Rodgers was 26-for-43 for 244 yards with a touchdown, but was sacked four times and threw two interceptions.
"It was a frustrating game," Rodgers said. "We spot 'em 14, score 30 in a row and they get 20. I played poorly, and the defense played well enough for us to win."
Bengals QB Andy Dalton was 20-for-28 for 235 yards with two touchdowns.
