how can the offense NOT take a step back?

I think it is a given that the Saints won't need to pas as much this fall. With that in mind, some of Graham's production in terms of will be irrelevant. With Spiller in there, more production will be directed towards him. Finally, since Graham was more of a hybrid than a traditional TE, some of his production will be absorbed by Coleman.

Doubts about the OL are justified. However, the play calling can be adjusted to offset the lack of strength in the guards by rolling the pocket more and quick slants if needed.
