In the 1960s and 1970s the greatest coach of all time was at him prime. John Wooden, known as the 'Wizard of Westwood', led his UCLA men's basketball teams to 10 championships in 12 years, with 7 consecutive national titles and back-to-back undefeated seasons. Their success was unlike anything I've seen throughout my own life and find the teachings from this magical coach to be incredibly valuable.
John Wooden didn't coach aggressively. He was more of a philosopher than anything. He led his teams by prioritizing the values and personal development of the young men on his team. This focus on the person not only benefited each person as a player, but more important it impacted the person.
John Wooden was known for writing several best-selling books on his coaching strategy and philosophy and the video below will give you a great introduction to his body of work and the impact he made. Enjoy!
