Saints agreed to terms with S Kevin Kaesviharn on a four-year, $10 million contract. The deal includes a $3.25 million signing bonus. Kaesviharn adds a veteran presence to a youthful secondary, but his play-making ability can't be overlooked after he picked off six passes as a reserve in 2006. The former XFLer will at least help in nickel situations, and could start as Roman Harper rehabs from his torn ACL. Titans signed CB Nick Harper to a three-year contract. In the process, Tennessee steals a solid starter from an intradivision rival, but Harper doesn't have any recent experience in the man-to-man defense the Titans run. Still, they need insurance because Pacman Jones' status for 2007 is uncertain. Terms of the deal are unknown.
