I like Dez, and was all for the boys drafting him. But he needs to focus more in the game and his assignments. He did get 105 yards but he could have had 200. He is going to drop some, but the mental errors are hurting the team, causing ints and more grief for Romo. He should be Romo's #1 guy, and I don't think Romo trusts him as such.
Its good for him to take responsibility not just vocally, but mentally and physically. Actions speak louder than words, so they say.
