I don't think there's a huge drop off from Kincaid to Knox to be honest. Kincaid is certainly a smoother athlete but I haven't been overly impressed with his ability to be at the right spot at the right time for Allen to deliver him the ball. I don't think it affects our game plan whatsoever.
The only thing with Kincaid being out is it makes it that much more important that Cooper plays. Most teams have been scheming to take away easy throws to Kincaid, KC won't have to worry about that now. At least with Cooper out there they have somebody to devote extra attention to and that will open up opportunities for everyone else.
