We'll take a daily look at where the Vikings' roster stands at the moment position-by-position leading up to our NFL Combine coverage on Thursday.

Position: Secondary

On the roster: Xavier Rhodes, Harrison Smith, Jamarca Sanford, Josh Robinson, Robert Steeples, Brandan Bishop, Robert Blanton, Mistral Raymond, Andrew Sendejo, Shaun Prater

Free agents: Chris Cook, Marcus Sherels (restricted)

In the final part in this series, we'll analyze the 31st worst pass defense in the NFL last season starting with the cornerbacks. The Vikings will have to address a glaring need at cornerback either through the draft or free agency

Chris Cook will finish his four-year stint with the Vikings without an interception. The second round pick in the 2010 NFL Draft couldn't stay healthy over the last four years and failed to play a complete 16-game season. It's hard to see the Vikings bring him back in the offseason.

They already have two young cornerbacks in Xavier Rhodes, who injured his ankle late last season following a solid rookie season, and Josh Robinson, who finished the season on injured reserve due to a fractured sternum. They probably need to add two more new faces at the position with Marcus Sherels as a restricted free agent as well.

Safety is perhaps the only position on defense that won't have any turnover with Harrison Smith and Jamarca Sanford. Smith suffered a turf toe injury that forced him to miss eight games last season. Sanford was excited once the Vikings announced the hiring of head coach Mike Zimmer and looked forward to his aggressive style of play, which should fit Sanford well. It'd be difficult to find upgrades from both safeties in the offseason.
