Hankerson, Little, Boykin, and Salas are the NFL version of discarded tickets on the ground a horse track. 99.99% of them are losers but there will still be a guy looking through them. At least with a draft choice you have the mystery of the unknown.
The '05 Saints had Az Hakim, Devery Henderson, Michael Lewis, Joe Horn, Donte Stallworth and Nathan Poole. A decent set of WRs. They picked Marques Colston in the 7th round the next Spring. I don't think they were sad about it.
