- The Lions have to stop with the penalties. They can't continue with a major penalty or two per series and expect to win this football game. The Packers aren't the Panthers. The wiggle room simply isn't there.

- At least the Lions maintained possession of the football during the first half, keeping Aaron Rodgers and the Packers offense off the field. The Lions defense is playing well after adjusting to the Packers no-huddle offense to start the game.

- The Packers are bracketing Calvin Johnson with Charles Woodson and a safety, but the Lions still have to take a shot or two down field. At this point, their playcalling is not aggressive enough.

- Packers wide receiver Jordy Nelson is an excellent player. Presents one-one-matchup issues for the Lions, who must roll their coverages to Greg Jennings.
