I saw this article on ESPN:

All it says is that the 49ers have hired Greg Manusky to be their DC. He came from the Chargers where he was their linebackers coach. I'm confused...they would rather have another linebackers coach be there DC than their own linebackers coach?
Does this mean they think they are going to lose Singletary ?
