Joe Montana never did it. Neither did Steve Young or Y.A. Tittle. Even the architect of the West Coast offense, Bill Walsh, could only imagine such a massive mark. Of all the Hall of Fame quarterbacks and coaches in the history of the San Francisco 49ers, leave it to Alex Smith and Jim Harbaugh to set a new standard. Smith threw for a season-high 303 yards and three touchdowns, Frank Gore ran for 106 yards and a score, and the 49ers amassed a franchise-record 621 yards in blowing by the Buffalo Bills 45-3 on Sunday.
