The Green Bay offense rolled up 402 yards and the team committed just three penalties, but McCarthy found holes to poke in Sunday's performance.
The most notable failure was in the running game, in which Alex Green gained 35 yards on 20 carries, an average of 1.8 yards per carry.
"I wasn't real happy with the production in the run game," McCarthy said. "I thought we left too many hard yards on the field. There were too many 1-, 2-yard runs that should have been hardball 3-, 4-, 5-yard runs. We need to improve that aspect of our offense."
