Robinson is the bigger boom player who has had a TD in straight games. Samuel, though, looks to have the eye of Kyle Allen (5/53/1 on 7 targets vs AZ). I really like Samuel (playing him myself) since he looks like he is getting the separation, but didn’t have a fully capable QB to throw him the ball. He is more than able to get by the HOU CBs.
I am leaning Samuel, but Robinson can match with one route. It really depends on your team and of this is a boom play or if you are looking for stable pts
