Anyone have any DC candidates?

I'm going to assume Leslie Frazier contract will expire and not be redone.  Before anyone comments that it doesn't matter Lovie is the DC.  I don't believe that for one second. I believe Leslie Frazier and Lovie have somewhat the same personality.  I think Lovie and Rod worked so well in Chicago is because of Rod's firery personality is a good compliment to Lovie. I don't think Lovie will balk at turning over play calling duties.  He didn't do a lot of it in Chicago and from what I can tell when he did the DC was out soon after.Any thoughts?  My suggestion is Jim Schwartz, I'm not a fan of him the HC but what he did in Buffalo last year at DC is impressive.
