1978 Steelers 21 vs Seahawks 10
After a scoreless opening quarter (thanks in part to a case of drop-itis by Steeler receivers), Pittsburgh opens up a 14-0 lead in the 2nd quarter on a pair of Bradshaw TD bullets (Swann & Thornton). The Steel Curtain applies steady pressure all afternoon, sacking Zorn 4 times (2 by a seemingly unstoppable L.C. Greenwood) and forcing several turnovers, including a fumble recovery and a decisive INT by Lambert and a forced fumble/recovery by Ham.
But Seattle's potent young offense, lead by Jim Zorn and Steve Largent, keeps fighting and narrows the score to 14-10 early in the 3rd quarter. The Steelers -- who seem a bit sluggish at times, falling victim to their own mental errors throughout the day and leaving a lot of potential points on the field with empty red zone trips -- ultimately put the game away with an impressive marathon 16-play, 75-yd TD drive capped by a Harris TD on 4th and goal (several minutes of this drive are missing), and the Steel Curtain closes out the win by forcing Seattle turnovers on their final two drives.
