obviously people are comparing the performances of GB and Dallas O-line versus Philly's D. The thing is, it isn;t just the lines of course, it's the lines plus the QB*. And Rodgers is so vastly superior to Romo that he will make a line look better. (I didn't get a chance to see the Dallas game, so I don't know how bad the line versus Romo played in that game)
*and RBs, but that's probably a wash or slight advantage to Lacy.
