He's usually spent a majority of his time lined up outside, if I'm not mistaken, though he definitely can operate out of the slot.
Call me greedy, but I still think Justin Jefferson in the 1st would put the cherry on top for this offense, and he'd get to work out of the slot - where he dominated last season - with Thomas and Sanders on the outside and Cook at TE. Throw in a healthy Kamara and it would be an embarrassment of riches for Brees.
I get that we have more pressing needs, and it will depend on who's there when we're on the clock. But I can dream.
