Steelers coach Mike Tomlin implied on Monday that he will make significant lineup changes heading into Thursday's game against the Browns. "It's appropriate at this point to acknowledge we have an undesirable pattern of behavior, which produces a series of outcomes that are not what we're looking for," Tomlin said. Pittsburgh is 6-6 after losing their fourth straight game on Sunday. "Moving forward this week and beyond, we can't continue to do what we've been doing and assume that that pattern of behavior is going to change and those outcomes are going to change. So we're analyzing all aspects of what we're doing here, specifically this week, and are going to be aggressive in terms of looking at potential changes in not only what we do schematically, but who we have do it in all three phases," he added.
