Just off the top of my head, I remember the Bills beating a 10-0 Giants team, a very good 49er team in the "no punt game," an undefeated Rams team (with Riech at the helm) on Monday night and the Dolphins (who were pretty decent then) twice a year. Let's see, they also beat Elway's Broncos in the playoffs, Montana's Chiefs, the Raiders (who were among the fastest teams of all time) more than once, and (forgive me for typing this twice) they owned Marino.
