If the Titans get rid of him I would love to have Williams back as a Defensive End with an offseason to learn the position.  At a good price of course.  He was miscast as a Nose Tackle in Denver and I think he is a tweener between end and tackle.  That makes him perfect for Defensive End in a 3 - 4.  The Broncos talked about playing him at End but I don't think he got many snaps with the Broncos at DE.
