I remember that, I think Kamara made a comment that the offense was going to use motion now and that was attributed to adding Carr to the offense.
What has happened so far? In the passing game, the Saints have the lowest rate of using motion (12.0%) while being middle of the pack in net yards/attempt (5.7 yds/DB).
That said, talent is still a need, and motion isn't a cure all. The Falcons rank 4th for motion usage when passing, but are the 4th worst team in net yards/attempt (4.5 yds/DB). The Giants are another team--9th in motion usage, 6th worst team in net yards/attempt (4.6 yds/DB).
