GREEN BAY, Wis. -- A pile of halftime observations from Lambeau Field, where Green Bay leads Chicago, 17-3:
We noted Green Bay's early pass efficiency, but as the half progressed the story quickly became how well the Packers were able to run. The Packers' offensive line is pounding the Bears, who have done a good job this season in run defense, and tailback Ryan Grant has 105 yards in the half. Overall, the Packers have grossed 138 rushing yards in the first half -- almost twice total the Bears have been giving up per game this season. For the most part, Grant and backup Brandon Jackson are getting three or four yards downfield before they're even being touched. Surprising.
Bears quarterback Kyle Orton is not himself. Twice he has come up limping after relatively mild shots to his right ankle. He has completed only five of 10 passes, and many of them have floated.
I haven't noticed a big drop-off at middle linebacker for the Packers after A.J. Hawk replaced the injured Nick Barnett. Chicago tailback Matt Forte has 60 yards on 15 carries, but it's not like you've seen receivers running open down the middle of the field.
The Packers missed a sure touchdown when Aaron Rodgers underthrew Donald Driver in the middle of the field during the second quarter. Bears linebacker Brian Urlacher, who was chasing Driver on the play, turned around to find the ball in his chest for an interception.
We had a James Jones sighting -- briefly. The oft-injured Packers receiver caught an 18-yard pass to convert a third down in the second quarter, but he came up from that play limping. Jones has struggled for most of the season with a knee ailment.
Packers placekicker Mason Crosby converted a 53-yard field goal near the end of the half. I'm sure a few Green Bay fans are wondering where that accuracy was at the end of last week's game at the Metrodome.
Unless I missed something, which is always possible, Orton has not looked for receiver Brandon Lloyd.
