Waiver wire vs current players

I have Taylor Gabriel on my team right now, and was thinking about dropping him for Kenny Golladay... thoughts? Other noteable players on the wire: Robby Anderson, Rex Burkhead, JJ Nelson, Devin Funchess, Deandre Washington, Dion Lewis, Chris Conley. I am a win now team, finished 2nd last year. Gabriel would maybe make a start if Julio gets injured and my wr are on byes. Any advice is welcome.
