Twenty years ago tonight, the result of the ''Miracle on Ice'' was well known before ABC showed it in prime time. The live Lake Placid scene behind the host Jim McKay might have been a giveaway that the 1980 United States Olympic hockey team had defeated the heavily favored Soviet Union, 4-3.
Joyous, smiling fans raised a banner saying, ''Go for Gold.''
ABC had tried, unsuccessfully, to shift the start from 5 p.m. to 8 p.m. What some have called the greatest sports moment of the century wound up on tape delay.
But McKay was not a spoilsport, saying: ''The events you're going to be seeing tonight have been completed. It may be that many millions of you know the results. However, we said at the beginning we would not tip the results.''
The most striking thing about the game, to be replayed tonight at 9 o'clock Eastern time on ESPN Classic, is how refreshingly clean it looks. No on-ice or dasherboard ads, no continuous score and clock, few graphics, no behind-the-goal cameras, no rinkside reporters and few crowd shots (among them, one of Jamie Farr).
The game's one unnatural additive: blue dye to make the ice more telegenic.
The director Ron Harrison, a veteran of 15 years at ''Hockey Night in Canada,'' used three cameras to tell the evolving drama. It was enough. ''It was basically 'Hockey Night,' '' he said. ''Stick with the story.''
He received only one instruction from Roone Arledge, then the president of ABC Sports. ''He wanted to see the puck, that's all,'' Harrison said.
The broadcast is also remarkable for the deftness of its announcers, Al Michaels and Ken Dryden, who was especially valuable in describing the American team's defensive lapses. Michaels had called one hockey game before the '80 Winter Games -- at the '72 Winter Olympics in Sapporo -- and Dryden had called none.
''If I hadn't grown up as a hockey fan, I'd have been worried,'' Michaels said. ''But I knew the game, understood it and loved the game, and by the time we called the U.S.-Soviet game, we'd done 14 or 15 games that week.''
Michaels and Dryden practiced more by playing a tabletop hockey game in their hotel room. Without much else to do, they familiarized themselves with the foreign names playing for coming opponents of the American team.
''We played it every night,'' said Arthur Kaminsky, Dryden's lawyer and hotel roommate. ''Michaels is saying, 'Kasatonov to Krutov to Kharlamov.' ''
Michaels recalled: ''Dryden was the most book-smart athlete I've ever worked with, yet he played this muck-muck style of tabletop hockey. I'm trying to play Soviet-style offense and he's just whamming the rod of his defenseman to knock my goalie off his hinge."
