Starting position wasn't good. New Orleans average the 30 yard line. Packers averaged the 18 (this was hurt by the penalty on the big Davis return).
But the second half offense looked like this:
GB 25 yard line, 5 plays, 18 yards. Punt
GB 19 yard line, 10 plays, 38 yards (plus 15 on penalty). FG
GB 10 yard line. 3 plays, 6 yards. Punt
GB 25 yard line.3 plays, 4 yards. Int.
I don't think that can be defined as moving the ball. McCarthy was mad as he gets publicly over the second half and this was the main reason. Whatever they cooked up at half time backfired. In the first half (with one huge Jones run) they had 195 net yards. In the second half, they had 65.
C'mon. Defense wasn't good. But the second half offense was putrid.
