The game before that was one of my favorite memories of not just Fergy but of the 1980 team. In week 15 Joe had his ankle crushed against the Patriots.
The following week the Bills had to win against the 49ers on the road to beat the Pats for the division title. In a rainy, mud soaked field in San Fran, the OL protected him so well, that he left the field without a single spec of dirt on him....while everyone else on the team could barely tell what their jersey number was because of all the mud.
If you have a copy of the book RELENTLESS read page 287.
Classic Fergy!
