PITTSBURGH -- One of the most pressing needs for the Pittsburgh Steelers is at cornerback. The trading of Joey Porter Jr. may have been justified, at least if you ask the organization, but it also left a glaring hole in the defense.

Without him, the Steelers lack a number one cornerback. Furthermore, their inability to play man-to-man coverage is beginning to be taken advantage of. The team's reliance on soft zone coverage is no longer effective, and their lack of foot speed continues to show up on film.

That's why the Steelers need to land a starting cornerback before the NFL Trade Deadline. These five defensive backs could all fill the void in Pittsburgh as they look to upgrade the secondary.
