You're crazy if you think Sean Payton is going to completely ignore the offensive side of the football in this draft. After shoring up the pass rush, he is going to aim to shore up the edges of his pass protection unit.
But remember also that Payton is a mad scientist who loves new toys. Don't think he hasn't spent a great deal of his time off the past year imagining new offensive concepts and studying some of the game's best offenses.
Of course, New England has two dynamic tight ends, and as such they have one of the best offenses in the NFL.
Rob Gronkowski and Aaron Hernandez are not clones, but they are fine complementary pieces. Gavin Escobar is nearly a clone of Jimmy Graham—a guy with a long, angular body who excels at snatching the ball out of midair in traffic.
Imagine the four vertical plays the Saints love to run with two tight ends like that running up the seams. Defenses could not stop it, ever.
