The interviewer wants you to put yourself one of your player's shoes, if you haven't done this before you should considering doing it. It helps coaching understand how their message is coming across. For this question think about a few qualities you want to have as a coach and then think if you believe your players would see you that way, if yes explain why to the interviewer- if not it would be best to pick another quality.
There is no right answer for this question as long as you back up your answer with why you believe your players would describe you with those qualities.
