We need a big H back who can both run and catch. We need OL, RB and a proper TE. I'd probably look to pick up the best interior lineman, an Hback, a RB and a TE in that order.
The Saints are a weird team, they brought in a new Offensive coordinator and the only player they drafted improve the Offense was an OT. They traded up in the second to gets corner. No free agents of note either. Never seen anything like it.
