Recently read somewhere that the lack of creativity was due to the lack of perimeter options in the offense. Just before Brees retired and even last year as Olave and Shaheed were figured out it was MT and nobody else. Perhaps you could have done more things w/ Kamara if we had stronger backfield options but it was only Ingram as a secondary runner.
This year we've added TE's, building on Thomas returning Olave and Shaheed, and then adding two RB's which gives Kamara a chance to be more of a receiver. Saints have far more short area options than they've had in a while.
