Wilson bounced in and out of the starting lineup in Detroit over the past four seasons, with his stint highlighted by last year's career-high 98 tackles. The 30-year-old could serve as the No. 3 safety in Indianapolis, where Malik Hooker and Khari Willis are expected to be the starters. The team also has rookie third-round pick Julian Blackmon, but he's still rehabbing from an ACL tear he suffered in December.
