I'm starting to warm up to Courtland Sutton, especially since he ran a 6.57 3-cone drill at the combine. This was 3rd best among all WR's at the combine and his 4.54 40 wasn't bad either at his height. My main issue with him was how he would catch the ball. In tape he seemed to be more of a clapper and his hand placement wasn't that good, although he did catch the ball much better at the combine.
Currently he is working out with Boldin, who is helping him with his route running and separation skills.
