When it comes to the offensive side of the ball, the Pittsburgh Steelers are very nearly a complete unit—assuming, of course, that their franchise quarterback indeed returns. They have their starting offensive line cemented in place, and even some solid depth. They have their running back, and their fullback. They have their top receiving threat. The only areas of uncertainty are at the tight end position, and in the second wide receiver role.
And they may already have the answers to those questions in-house, but it will be a matter of time before they get it sorted out.
