#40 January 1, 1989 Bill's Last Win
Not this year. In what would be Bill Walsh's last ever Candlestick win, Jerry Rice scored three first half touchdowns, Roger Craig added two in the 4th quarter, and the Niners began their third Super Bowl playoff run with a 34-9 win over the Vikings.
The Niners had 6 sacks; Ronnie Lott had two picks - a week later the Niners went into Soldier Field, beat the Bears, and went on to win the Super Bowl.
#39 is tomorrow.
