Jared Cook is not as fast as Vernon Davis, but he is a better blocker per what the experts have stated. Also, Vernon Davis just got a ring didn't he? I'm guessing he's going to be less hungry for his 2nd ring than Cook is for his 1st ring.
The decision is an easy one, Jared Cook. He has more upside, younger, better player and I believe is more hungry to win and also has incentive to produce for a big contract. And there is also the fact that the Packers have him so I might be a little homer on it too.
