There is all sorts of video around of Bill Walsh breaking down plays and describing his football philosophies. The 49ers organization has a lot of video in their own archives, but every so often something interesting will pop up online.
The latest we see is from after Super Bowl 23. The 49ers beat the Cincinnati Bengals 20-16, winning the game with an 11-play, 92-yard drive in the final 3:20 capped by Joe Montana finding John Taylor in the back of the end zone.
Someone found some video showing Bill Walsh breaking down the specifics of the game-winning touchdown pass.
