I would like them to maybe get another edge or a RT. Niang is a OK, but can't stay healthy. At edge Karlaftis is showing flashes but is a rookie. The same with Skyy Moore. They say it takes a WR a year to fully grasp Andy's playbook, so I think we'll be seeing more of him as the season progresses.
As far as Pacheco goes, Helaire is like Niang, he can't seem to stay healthy. But until that happens I think it'll be about the same as it is now.
