Early in my career, I drove Hall of Fame49ers coach Bill Walsh around in his car. Oftentimes, our conversations centered on my goals -- how I could reach them, and what I ultimately wanted to become. At that time, I thought I really knew the game of football. But in reality, each time I viewed the All-22, I was just watching film. Not studying, not improving, not learning. Just running the machine. As Coach Walsh would tell me, I did not understand the play, so I couldn't correctly evaluate the player. Each time you watch the All-22, you must be able to simultaneously assess the play and the player to understand both. This is not easy for some in the NFL, let alone fans who want to access the coaches' tape.
