Unless we want to kick the can on some more contracts, this is the Saints filling out the roster with a journeyman. Not a big deal. It's a depth (camp signing at worst) move. He flashed in Dallas, probably better than some of the guys on back end of the WR room in 2023.
That is all he is. A little odd to sign players like he and Peterman this early in free agency, but they are the type of late signing to fill out a roster for camp.
