The San Francisco 49ers had one of the NFL's best defenses last season, but that doesn't mean they can't address that side of the ball early in the 2013 NFL Draft. In particular, a secondary that was exposed by Matt Ryan and Joe Flacco during the playoffs could get a face lift according to mock drafts compiled by Dane Brugler of CBSSports.com and Dan Kadar of SB Nation.

Washington cornerback Desmond Trufant is Brugler's pick for the Niners with the 31st overall pick. Trufant performed very well for scouts during Senior Bowl practice in Alabama. He has NFL athleticism and size at 5'11, 190 pounds. He was a play-maker for the Huskies, though he may need to add some strength to his frame if he is going to handle big-bodied NFL wide receivers at the line of scrimmage.

Kadar likes Florida International safety Jonathan Cyprien for the 49ers. Cyprien has been one of that fastest risers up draft boards in recent weeks, also thanks to a solid showing at the Senior Bowl. Kadar describes him as a "fluid safety prospect that can run and hit." At 6'0, 209 pounds, Cyprien has a nice frame, too.
