My father let me borrow a two DVD set entitled "The San Francisco 49ers - The Complete History" and while there was a lot of good content on the DVD's there was one section called "Quarterbacking by Bill Walsh" that was the most impressive video I have ever seen about football.
Bill was explaining the quarterback position. His pupil was Joe Montana. He also had Roger Craig, Jesse Sapolu, and Dwight Clark. It appeared that it was filmed around the year 2000 so all players had retired.
Bill explained a half dozen or more plays in detail. He also talked about the footwork necessary for each type of throw. He showed how different 'reads' are made and how to fool the defense with head movement and fake hand-offs.
All the while he is making Joe throw the ball to Dwight or Roger or he is handing off the ball to Roger. Bill went into great detail about the pass to Dwight Clark in the 1981 Championship game. He showed the play as it was diagrammed. It was supposed to go to Freddie Solomon, but Dwight was open as the alternate receiver. The play had been designed to be throw high so that if Dwight could not retrieve the ball then no one would be able to catch it. According to Joe Montana, they had spent many, many hours practicing that play throughout the season. The play worked exactly as planned.
I really, really enjoyed this segment and I encourage anyone who enjoys the game of football to watch it. It does not matter what you think of the San Francisco 49ers.
