I recently heard an esteemed celebrity football announcer say during one of the Sunday games that the referee was going to change out the football. Change out?

What does it mean to change out? Is it more important to change it out than to simply change it? Does it sound more exciting, more challenging, more game-changing to change something out?

This wasn’t the first time I’d heard the expression change it out when change it would have been correct. I’m not even certain whether changing something out really is the same thing as simply changing something, but what I do know is that the referee was going to change the ball.
