I don't know much about AJ Hawk except that he is a stud linebacker. I'll agree with your assessment that he is the only one worth trading up for. My question is, if defense is the only thing worth trading up for, why do it?
In past years, I've thought that if Dallas did not acquire one certain player, the entire draft would be a disappointment. The Dallas offense really needs value, and I'd like to see some young talent added to the group. Trading down, and acquiring two players of Anquan Boldin or Steve Smith quality would be an excellent idea.
The last draft showed that Dallas can pick solid players throughout the draft, I'm not going to lose it if "my player" doesn't get picked.
But hey, I'm not knocking AJ Hawk, he will probably do well wherever he goes.
