I voted Corey Williams because I think that a better pass rush will improve the entire defense, while Lance Briggs may not be as affective without guys like Brian Urlacher and Tommie Harris around him.
Good reasoning, can't fault that at all. I would be happy with him too. (OR anyone on that list for that matter)
Observation could be true on Briggs, Urlacher has always been a good MLB but I think he got better with Briggs next to him. Also I have seen Briggs play alot without Tommie Harris (was injured) and he still did pretty good. Not to worried about Briggs just being a product of the system. But it is a concern albeit not a large one for me, but its underlying)
