The Saints don't have many true needs.
There are several spots where the team could get better, but there are only a few where there is dire need to plug a gap. This sets up for an interesting offseason because New Orleans could bring in just about any player at any position and be able to justify making such a move.
The only things the team needs to do is add a backup quarterback, whether that's Chase Daniel or someone else, and another defensive end. There are plenty of needs, and assuming Drew Brees is retained, backup quarterback is a weak "must" considering Taysom Hill is already on the team.
