First let's start with the bad.
While I think Sam Shields can make the team as a CB, I think he won't as a KR/PR. He muffed a punt that was saved by a Brandon Underwood interception in the end zone.
I also thought Underwood was all over the place, but because of Woodson and Harris not playing he was starting when he would normally be the third or fourth CB—not too big of a concern.
This defense also needs Clay Matthews healthy for the start of the season. They generated almost no pass rush with the first team defense.
The special teams also seemed bad. They struggled on coverage and turned great punts into bad ones because of how many yards they gave up on returns.
Ryan Grant also struggled, but he only had two carries, so it's hard to tell. He appears to be fine after suffering a blow to the head.
As for the positives, even with a mediocre running game, the 1st team offense looked unstoppable.
Aaron Rodgers went 12-13 for 159 yards and a TD. Most importantly he wasn't sacked.
JerMichael Finley played well, but with all of the attention on him this offseason it seems that everyone's forgotten about Greg Jennings.
He scorched the Browns' defense on his two catches, including one for a TD. At times he was wide open and faced one-on-one coverage.
The Packers should just put James Starks on IR for this season because Quinn Porter and Kreg Lumpkin both look like viable thrid-stringers.
The bottom line is it's still only the first game of the preseason. The final score isn't that important and working out the kinks is what the preseason is for. I'm looking forward to Seattle next week.
