The fact that neither team has a winning record doesn't diminish one bit the intensity of the rivalry between the Ravens and Steelers.
If it is not the most historic series in NFL history, it's as intense as any. Just listen to what John Harbaugh told his players this week, heading into their visit to Pittsburgh.
"One of the things that was said in the meetings ... is that you're not a Raven until you beat the Steelers," Harbaugh said. "We have some young guys that still need to beat the Steelers."
To remain on top of the AFC North, that's exactly what Baltimore (2-2) must do.
