Saints have a great OL and RB, extremely smart play caller some speed WRs and a strong armed QB. They can do some damage still...
Not sure about the Packers new defensive scheme yet, but neither might the Saints especially with a new QB.
But I think this SHOULD be the Packers offense should still win this game, because the Packers should be able to control the interior line with the Saints weak at DT, then having their best DT suspended, and former Packers DT Ringo being a starter on their depth charts. So the Packers should be able to run the ball up the middle, and therefore control the clock. Plus LaFleur system and Rodgers.
