Quarterback Ben Roethlisberger is projected for 15.20 points, which actually might be a bit conservative for Roethlisberger, given the emergence of Antonio Brown as a top target in the past few weeks and the injury to the Bengals' Leon Hall.
Running back Rashard Mendenhall is projected for 11.27 points. He'll probably get there if he has a touchdown, and he had two in his last meeting against the Bengals, but he's only had one 100-yard rushing game this year.
Wide receiver Mike Wallace is projected to have 9.37 points, although his big-play ability means he could easily top that total in one play.
Fellow wideout Brown is projected for 8.09. Brown has actually topped that points total in all of the last five weeks, so it's all a matter of whether Roethlisberger keeps throwing to him.
Other than the Steelers defense, that probably covers all the Steelers you should be playing.
