One center who was rumored to have drawn the Chiefs interest is Oakland Raiders free agent center Stefen Wisniewski. Per reports, Wisniewski has visited the New England Patriots and Jacksonville Jaguars.
The Raiders obviously don't need Wisniewski after signing Rodney Hudson from the Chiefs in free agency. In the first few days of free agency, the Chiefs were rumored to have interest in Wisniewski but as far as I know that's as far as we've gotten. Wisniewski's two known visits are New England and Jacksonville, not Kansas City.
The Chiefs only have a few million in cap space and still need to sign their draft picks so they might have to make a few moves to create the space to sign Wisniewski -- if they're interested in him.
