Marquez Callaway

He's already getting snaps on offense and was the next man up behind Harris as a KR/PR which tells me the Saints have plans for him.

He'll probably get the snaps on offense that Harris' would normally get leaving just a few gimmick plays for Harris. Harris can remain at PR. I know it's exciting to see a little 5'6" 170 lb guy run around, but there's not a great track record of those guys having long successful careers and most are injury riddled.
