All season, the Steelers haven't hesitated to make changes along their offensive line. The latest example came in Week 12, when they benched starting OLG Chris Kemoeatu, replacing him with Doug Legursky. The OLG spot is a key one relative to the Steelers' running game; though the Steelers mostly run right, the left guard is routinely asked to pull to that side. Kemoeatu, who's listed at 344 pounds, plays with power, but Legursky has the edge in agility. Legursky began the season as the right guard, where Ramon Foster has taken over the starter's role. Legursky, who has missed time with shoulder and toe injuries, is also the top backup center, and he played extensively in the middle against Kansas City when C Maurkice Pouncey — the only Pittsburgh lineman to start every game this season — left with an illness. One lineup change that has especially paid off for the line is at left tackle, where Max Starks, who wasn't on the roster at the beginning of the season, has played well since replacing Jonathan Scott.
