It was a good drive killed by a penalty on an attempted pass play. The fact that Rodgers had to twice pull the ball down and run on that drive might indicate that the Lions and had made some defensive adjustments, and what had worked so splendidly in the 1st half wasn't working as well now.
The main difference between 1-8-2 and 1-5-0 may have been the fact that the Lions had some long scoring drives in the second half. I understand the frustration people have. But I wonder how many coaches with a 21 point half time lead and a defense minus 5 starters wouldn't have tried to run the ball.
