There is much focus on the Lions' issues at cornerback, but especially if they re-sign pending free agent Chris Houston, they have much more depth at corner than at safety (last year's 6th-round pick Jonte Green played surprisingly well as a rookie and 3rd -round pick Bill Bentley will be back). But cornerback would still hardly be categorized as a strength.

Desmond Trufant: Most underrated player in this NFL Draft

I do see Alabama cornerback Dee Milliner as a possible pick for the Lions at fifth overall. There were questions about his speed. He answered them at the combine with a 4.37 40 time. Washington cornerback Desmond Trufant will also rocket up the draft board. He performed extemely well duirng the Senior Bowl workouts and ran essentially as fast (4.38) as Millender at the combine. Trufant is Millender's equal, in my opinion, as a prospect.
If the Lions draft a corner in the first round, they still need to augment safety. Is it worth a second-round pick? The talent at safety is certainly there to justify an early pick. Eric Reid from LSU is a tremendous player, who worked out surpriingly well at the combine. And remember this name: Jonathan Cyprien from Florida International. He missed the combine workouts because of a hamstring injury, but is an outstanding player, who showed well at the Senior Bowl. Neither would be a stretch should they fall to the fifth pick of the second round.
As for an edge rusher, it's still on the plate in the first round for the Lions. LSU's Barkevious Mingo and Oregon's Dion Jordan worked out exceptionally well. BYU's Ziggy Ansah is beyond intriguing as a pure athlete. It could depend on whether they re-sign Cliff Avril during the free agency period.
