A head coach, senior coach, or manager is a professional at training and developing athletes. They typically hold a more public profile and are paid more than other coaches. In some sports, the head coach is instead called the “manager”, as in association football and professional baseball. In other sports such as Australian rules football, the head coach is generally termed a senior coach.

Other coaches are usually subordinate to the head coach, often in offensive positions or defensive positions, and occasionally proceeding down into individualized position coaches. (source)
