They did steamroll, but it was against the Steelers and Dolphins, teams that the Bills owned at that point (I would have liked to have seen them play against the Chargers).92 was the shakiest of BUF's SB teams. 91 scored the most points, 93 was a better defense, 90 their best overall team
Although I truly thought they would beat Dallas since they steamrolled through the last 2.5 playoff games before the Super Bowl. After going down 35-3 to the Oilers, they outscored opponents 91-16 the rest of the way.
Also, while the 1993 Bills did finish fifth in points allowed, they were 27th in total yards, 24th against the run, and 21st against the pass.
