Physical preparation and fitness.
Coach Wooden as usual sums matters up quickly. “The 3 keys to winning basketball are CONDITIONING, understanding the Team Concept and mastering the fundamentals of the game.” It is no accident conditioning comes first. It doesn’t really matter how great a player’s skills are or how tough they are mentally. If that kid can not get UP and DOWN the court quickly and constantly, he can not compete at a high level. Conditioning resides near the TOP of our pyramid for that very reason.
