Matt Ryan has an embarrassment of riches on offense, but was only marginally more efficient than Roethlisberger last season. Even Michael Turner, during his "disappointing" season, had more rushing yards than any Steelers RB, and more TD runs than all Steelers RBs combined. And there's no question that the Falcons had a better offensive line, better WRs, and better health, for that matter. All that helped Matt Ryan to a 99.1 rating last season, versus 97.0 for Roethlisberger. Furthermore, Matt Ryan has committed multiple turnovers in four of his five career playoff games. He takes worse care of the ball than Roethlisberger does. Roethlisberger is still the better QB.
