Colts S Khari Willis announced his retirement Wednesday after just 3 years in the league. Willis said he plans "to devote the remainder of my life to the further advancement of the Gospel of Jesus Christ." His retirement leaves an opening in Indy's starting lineup, with Rodney McLeod, rookie Nick Cross and Julian Blackmon looking like the primary competitors. Cross -- a 3rd-round pick out of Maryland -- looks most interesting from an IDP standpoint. He tested great at the Combine -- 98th-percentile 40, 92nd-percentile broad jump, 71st-percentile vertical -- at 6'0, 212 pounds. NFL.com's Lance Zierlein called him "the bouncer of the Maryland defense," lauding his "aggression and explosiveness." Zierlein also highlighted Cross' tackling ability near the line of scrimmage and in the open field, which sounds good for his tackle-collection potential in the pros.
