If the Saints could sign one more decent player what position should they address?

For me it would be either tight end or defensive tackle. While most of you would probably say no to a Jared Cook reunion (Even I can't forget the 2020 Playoffs against TB), for 1 year I'd take a flyer on him for cheap for one more chance to chase another Super Bowl. I think solidifying the defensive tackle position is a little more important and I would love to have Suh but we all know he's a mercenary that's all about dollars the Saints don't have.
