Mike McCarthy has said that the Green Bay Packers did not take care of the ball during their 17-0 pre-season defeat to the Arizona Cardinals.
The NFC North champions used all four of their quarterbacks during the game, but none of them could find the end zone.
The head coach told the Packers website: "Tonight's contest, not exactly where you'd like to start, 0-17, on our home field. Offensively, obviously, the turnovers.
"Our ability to take care of the football is something [we] stress. We didn't take care of the ball and we did not take the ball away. You have to take care of the ball and take it away.
"We've got a lot of film on a lot of guys. We'll take a hard evaluation in the morning. This is step one. This is where we are."
The Packers face the St Louis Rams next Saturday.
