There have been some pretty crappy years in the Marvin Lewis era, but I can't ever recall his teams being completely dominated on a weekly basis.... The only year I can remember so many blowouts was 2008 and that team lost Palmer pretty early in the season.
the Marvin Lewis resume basically states that he is a smart LB coach and defensive coordinator. Our line backers aren't that good, and he can't seem to get anything out of his defense.
