Underhill article on why the Saints O is so bleh

The lack of motion hasn't bothered me much, I barely noticed it, but the lack of play action had bugged me and has been quite noticeable. Of course, it helps to have an effective run game, but that doesn't mean that you shouldn't do it anyway, You absolutely should so as to try to get the LB's and any safety in the box out of position in coverage and give your receivers more time and space in the middle of the field behind the backers.
Agreed. I was really only using motion as one example (along with play action since both were issues last year, too).

I think it’s more that they’re symptomatic of a bigger problem: we’re not doing much that’s innovative and we’re not putting our players in positions to do what they do best (like the numbers on Michael Thomas and slants).
