Thumbs down: What's with all the penalties on the Packers, especially on the offensive line? The Packers finished with eight penalties marched off against them, which is four less than last Monday night when they had 12 enforced against them. Still, the Packers need to eliminate more of those mistakes.
Thumbs up: Second-year pro Brandon Jackson and rookie Kregg Lumpkin were impressive running the football. Jackson averaged 8.7 yards per carry and scored a key touchdown late in the game. Lumpkin had one carry for 19 yards.
Thumbs down: Coach Mike McCarthy should have held Ryan Grant out of the game. It was obvious that he is bothered by his hamstring injury and it showed in his stats. Grant averaged 1.3 yards per carry on 15 attempts for a total of 20 yards against a defense that gave up 318 a week earlier. Why not give Lumpkin a few more carries?
Thumbs up: Charles Woodson didn't practice all week because of a fractured toe, yet he showed no signs of the injury bothering him. He finished with two game-saving interceptions, including one for a touchdown.
Thumbs down: The safety help on Calvin Johnson's two touchdown receptions (38 and 47 yards) in the fourth quarter was non-existent. Johnson made it look easy after making the catch and breaking free for the end zone.
Thumbs up: Safety Nick Collins for actually catching a pass and then scoring from 42 yards out for the final score with 2:07 left in the game. Collins has had a history of dropping sure interceptions, but made his first pickoff since Dec. 31, 2006, when he had two against the Chicago Bears.
Thumbs down: The officials should have flagged Lions quarterback Jon Kitna for unsportsmanlike conduct for removing his helmet in disgust during Collins' interception return for a touchdown. The Packers could have kicked off 15 yards closer on the ensuing kickoff.
Thumbs up: Greg Jennings sure looks like he is becoming Green Bay's top receiver. Jennings had a career-high 167 yards receiving on six catches (27.8 yard per catch). His 60-yard catch and run from Rodgers in the fourth quarter led to a 39-yard field goal that gave the Packers the go-ahead lead, 27-25, with 5:17 left.
Thumbs down: James Jones and Brandon Jackson dropped consecutive passes in a drive in the third quarter. Plus, punter Derrick Frost let a high but catchable snap sail through his hands for a safety in the fourth quarter that closed the Lions to 24-18.
Thumbs up: Another impressive game overall by the Packers, who improved to 2-0 with a lot of momentum heading into an early NFC Conference showdown next Sunday night against the Dallas Cowboys at Lambeau Field.
