The Ravens and Steelers are set for a playoff grudge match on Saturday night in Pittsburgh. After splitting the regular season series 1-1, there’s not much between the two teams, except animosity. For the Ravens, there are plenty of reasons to hate the Steelers. They have a head coach who thinks he’s a linebacker and dirty players who seem to enjoy knocking Ravens unconscious. Torrey Smith doesn’t even like the Steelers’ grass.
