I do not think there has been enough attention to how Lacy's running style and body type is uniquely advantageous to the Packers. In the past, opposing pass rush has been a problem in part because of our continually makeshift offensive line.
The beautiful thing about Lacy is that his bulk size, power and running style make him a bruising back. I have read former players turned analysts analogize facing that type of running back to catching a heavy, falling sofa on every corner. That wears down defensive lines. Not only will Lacy get opponents out of that two safety back formation, but it will atrophy opposing defensive lines. So as the game goes on and Rodgers has the ball, that pass rush will become increasingly less effective.
I am really optimistic about this year. I hope we destroy anyone and everything in our wake, starting with Seattle and, should we meet, the niners.
