Wicks isn't the fastest WR, but his route running was strong. He is 5th on the team currently (Watson just passed him in a game Wicks was out injured) in receiving despite getting much fewer snaps. He kind of gives me some Donald Driver vibes - not big, not fast, just gets it done - type of WR.
Van Ness' knock was more on technique. I think there were some Qs about him holding the edge, but that doesn't seem to be an issue. Maybe if he was a 4-3 DL he would've been small?
He clearly does need more pass rush moves... kind of eerily similar to Gary in their rookie years.
