They are both in their third year, so I don't know if they would have developed enough to stay beyond their rookie deals. They needed to take huge steps this year and only took baby steps. Now, I thought Joseph was quite good in the preseason games, but in the camp footage, he was constantly getting beat. I'm sure that was a factor in the decision. At linebacker, I thought Harper outplayed Cox. Might could have kept them both because of the depth issues there, but we clearly think more of the safety/linebacker hybrids than we do Cox.
