Shawn Williams is worthless in pass coverage

[CoreyK]

I like Derron Smith far better than Shawn Williams. 

I think the only reason they go with Williams is that Iloka plays centerfield position (Free Safety) and Smith would ideally play same position as Iloka.  

That being said, just move Iloka to Strong Safety and throw Derron Smith in centerfield (free).  Shawn Williams can then move to Nickel LB but he should not be in pass coverage as a starting Safety for this team. 

When Burfict comes back I would go with this Nickel lineup:
LB Burfict
LB S. Williams

CB Jones
CB Kirkpatrick
CB Dennard/Shaw

SS Iloka
FS Smith

Dime
LB Burfict

CB Jones
CB Kirkpatrick
CB Dennard
CB Shaw

SS Iloka
FS Smith

I don't like Karlos Dansby so far in pass coverage at all.  Same goes for Vinney Rey and Rey M.
