Packers now have the best O-line in the NFL according to pro football focus. Rodgers has an avg of like 4-5 seconds to throw and if you can create holes big enough for Eddie Lacy aka Feast Mode aka the Elephant to avg 5.5 YPC then that is easily the best O-line in the game (statistically and the eye test).
That was simply amazing watching them stymie the Giants rush. I believe the OL won't hold up as well against the pass rush when they aren't on loose and familiar grass. So Dallas has no shot to get to the QB, not with just the front 4. However, in Rod I trust to figure out a way to get pressure.
