Pittsburgh Steelers vs Baltimore Ravens

Only in an extremely rare case would a rivalry less than 20 years old make it this high. But the Steelers-Ravens are an exception. They play in the same division, so they meet twice a year, but because they often have two of the best defenses in the NFL (six of the last 14 Defensive Player of the Year Awards have went to Steelers or Ravens), so it s obviously a special, extremely hard-hitting affair. Now, they ve met in the playoffs four times in the past decade and a half and they are almost always classics. This matchup is one of those that all NFL fans mark on their calendar in the preseason, you don t even have to be a Steelers or Ravens fan.
