Who said anything about "success of the O-line"? I said the team has been successful - to a great extent anyway. The O Line has never provided adequate pass protection and has almost never opened decent holes for the running game. We pass successfully because Rodgers is so damn good, both throwing accurately and with his mobility to get away from the rush. The only time we can run the ball at all is when there is deception - draw, misdirection, etc. Line up and run right at 'em, and it just doesn't work.
As for theory as you call it hahahahaha, overrated "stars" like Sitton and Lang leave and flounder elsewhere, while mediocre replacements come in and it's all about the same. We beat Seattle with scrubs at tackle, and if necessary, we'll beat Cincinnati and whoever else down the line that way.
As I said, the Atlanta game was a perfect shitstorm in a lot of ways.
