When it comes to free agency, as readers of the site are well aware, the Pittsburgh Steelers are very rarely active players in the open market. If they sign any outside free agents, it often comes in the form of a one-year veteran-minimum qualifying contract or two for a player designed to provide depth at a leaky position.
The Steelers routinely focus their efforts not on adding from outside of the organization, but rather keeping together what they have already built. After all, nobody will be able to come in and contribute as seamlessly as a player that has already been a part of the building process.
