If we were playing a game, like Madden, where you assign points for each ability and you have a limited pool of points, where do they go?
Are great hands that important if you are not open? Route running is worthless if you cannot catch. On and on it goes, which is why people like Kupp and Robinson have been so successful. Most cannot do even one of those things at a top level, but to have multiple guys able to do them is an incredible luxury.
McCutcheon might be great at catching and catching contested balls, but if he was out there on the field in a real game, I don't feel like he will be open enough to get the ball thrown his way. Against better competition are those interceptions, or batted balls?
