i think the greatest football game was in September of 1992 when the Buffalo Bills beat the SanFrancisco 49ers 34-31 in SanFrancisco. Both teams combined for over 1,000 yards of offense and there were no punts. It was the Bills running back Thurman Thomas who was the difference in the game. This was way before the NFL changed the rules to help offenses score. The Divisional Playoff game between the Bills and Chiefs last season was a great game but not the greatest in my opinion.
