What was the most dominating Rams victory over the Seahawks? It used to be the 1979 game, when the Rams won 24-0 and held the Seahawks to -7 yards (yes, that's a minus sign) and only one first down (which Steve Largent barely got). I think the 2017 game was even more dominant. It was 34-0 at the half, and the Rams could have made it 60-0 if they hadn't called off the dogs early in the third quarter. Finding a copy of the 1979 game (which for many years didn't seem to exist) was one of my most exciting moments as a Rams fan.
