First-round pick Marcus Peters has looked very good in camp and will start; he should be an upgrade over what they've had in the past. Phillip Gaines, a second-year pro with excellent coverage skills, will fill in for Smith before sliding into the third-corner role. As for Smith, he doesn't get a lot of interceptions, but he's a long, tall (6-foot-3) guy who knocks down a lot of passes. At safety, Ron Parker, who was re-signed, will help -- and, of course, the team is welcoming veteran Eric Berry, who fought his way back to the field eight months after being diagnosed with Hodgkin's Lymphoma. Berry, who can play a crucial role in making sure the secondary is lined up correctly, looked healthy and on his game in camp. Kansas City also signed Tyvon Branch and drafted cornerback Steven Nelson, to provide depth. Hall of Famer Emmitt Thomas does a great job with young players as the defensive backs coach, and I expect this to be a much-improved unit.
