The Pittsburgh Steelers rarely make a big splash in free agency, and 2013 likely will be no different considering their salary cap situation.
It's highly unlikely the Steelers will find the money to sign a marquee free agent. However, they almost always find the money to sign bargain free agents, and many of them contribute as role players.
We'll grade each positional unit in terms of how the Steelers could benefit from such a signing.
Here's our grading system:
A=No free agent signing is needed.
B=Free agent could provide depth.
C=Free agent could see significant playing time and compete for a starting job.
D=Steelers have a hole at this position that could be plugged with a bargain free agent.
F=If the Steelers sign one non-special teams free agent this offseason, it should be at this position.
