I just rewatched the 1st half and call me a homer, but I thought the offense played VERY well. While they certainly didn't play a perfect half, they played better than their press.
The OL gave Losman plenty of time and opened up plenty of holes for WM. They did allow pressure that ended the 2nd drive (FG) and on 3rd down of the 4th drive (punt).
The offense scored 3 out of 4 times.
WRT JP, I saw him make two 1st downs with his feet, prudently throw a ball away in the red zone, accurately hit several receivers on short routes, threw 2 long balls that drew PI (EM would have come down with one of them) and on a whole - he managed the offense rather well. His numbers weren't big, but he played better than they indicated. He did miss seeing a wide open EM.
I have not rewatched the 2nd half, which was much weaker than the 1st . I would not count the 1st and 2nd quarters as part of 10 consecutive bad ones by JP.
