... San Francisco 49ers are a team that has undergone a severe change of history and culture.

In the Super Bowl era, the 49ers controlled the 1980s due to the genius of their head coach and general manager Bill Walsh.

Walsh was an innovator who created the West Coast Offense that was a passing based offense used towards multiple receivers and if the receivers were covered, a running back or fullback could run out of the backfield to catch a short pass.

He drafted the great players of the 49ers like Joe Montana, Jerry Rice, Charles Haley, Roger Craig, and Ronnie Lott.
