Penalties are a factor, but IMO the more important factor by far is offensive output. If our offense falls flat then we're gonna lose. Period. Look at the game vs the Jets- Ravens only had 4 penalties for 35 yards (miraculous by this year's standards). But since Flacco and the offense did NOTHING, the Ravens lost. Given the fact that Ben, Bell and Brown will all be healthy this time and Jimmy Smith will be out, I see this as a game where the Steeler offense will put up big numbers and Flacco & Company will have to keep up if the Ravens are going to win.
