Despite injury concerns over the past two seasons, Philadelphia Eagles' cornerback Ronald Darby is still one of the better defensive backs in the NFL.

Darby has spent four seasons in the NFL, with his first two being in Buffalo and his latest two being in Philadelphia. In his first two seasons, Darby started all 29 games he played in and was one of the best young cornerbacks in the NFL. In those two years, he had 137 total tackles with four tackles for loss. Defending the pass, Darby had 33 passes defensed and two interceptions.

After his second season, Darby was traded to the Philadelphia Eagles. In his two seasons there, Darby has only played in 17 games, missing time due to injury. In those 17 games, Darby has 77 tackles with one tackle for loss, along with 21 passes defensed and four interceptions. In the Eagles' Super Bowl win over New England, Darby had four tackles and two passes defensed.
