ORCHARD PARK, N.Y., JAN. 20 -- Buffalo Bills Coach Marv Levy celebrated for about 10 minutes, then began setting up this week's schedule tonight after defeating the Los Angeles Raiders, 51-3, for the AFC championship.

Levy didn't know if the Bills would be playing the 49ers or Giants when he and his coaches began preparing for what is likely to be a long, odd week.

The Bills will fly to Tampa late Monday, then start Tuesday with the week-long retinue of early morning news conferences, afternoon practices and night meetings.

This is only the second time teams have had just a week to prepare for the Super Bowl, and Levy admitted he wasn't sure how to handle it.

"It's a tremendous difference," he said. "It's more than just saying, 'Well, gee, you've gotten ready for a game in a week all year.' You've got all the logistical problems, you've got to go out of town, you have to have a game plan for a team and we still don't know who it's going to be. There are a lot of diversions, a tremendous amount of media needs to fill. So it is more difficult. But it is also going to be more difficult for the team we play. So you have to adjust."

Each Raider brought six pairs of shoes because they didn't know if they'd be playing on ice, snow, wet or dry turf. As it turned out, they got a little of all of them. A light rain mixed with snow fell as the game began and turned to a steady snow by nightfall. . . .

The Bills were 10-0 at Rich Stadium this season -- the only undefeated team at home. . . . Today's game was the last for NFL referee Jim Tunney, who is retiring. . . .

The 51 points is the most the Raiders have allowed in a postseason game. Their previous worst was the 33 they allowed the Green Bay Packers in Super Bowl II. . . . The 41 first-half points by the Bills are a postseason record. The previous record was 38 by the Redskins in a 51-7 victory in 1983. . . .

Jay Schroeder became the 12th player to throw five interceptions in a postseason game. The last to do it was Detroit's Gary Danielson against San Francisco in 1983. . . .

Jim Kelly has thrown for at least 300 yards in three straight postseason games. . . . The Bills appear to have suffered no serious injuries.
