That is a pretty logical explanation Oviedo. But the emphasis that ownership has apparently put on an ability to run the ball with authority would lead me to believe that they see that they are in need of some top-tier talent on their O-line. The Steelers have always had one or two perennial Pro Bowlers on their line. They haven't had one since Faneca and Hartings left. And their running game has fallen off precipitously since then. They need to invest there for the future. You can develop back-ups and possibly even future replacements, but they need to draft starting quality guys. The current group is certainly serviceable, but C, RG and RT could all be upgraded IMO.
