Haloti has been the only one for the most part who has actually been doing anything inside. Maybe not having all the attn on him will allow him to be injury free.
You could have said that about a few guys 6 weeks ago. That was before an achilies and tricept tear. He could be becoming injurty prone. Also he is a talker and Harbs does not abide by that.

I don't see top 5 right away. They need to get their db's in order first. But the run is going to be so much better. They were basically a seive last yr.
