I think people are interesting and I always wondered about football teams.....the locker room......etc. You always hear about coaches handling players differently......pushing buttons and not pushing buttons. Isn't alot of this just whether a player is a introvert or extrovert? There are introverts that will tear your head off. And extroverts that will tear your head off. Their are captains that are introverts and extroverts. Coaches that are introverts. I have heard that defensive lineman might be more apt to be extroverts than introverts. And vise versa. Do they talk about this stuff in coaches school. Thanks in advance.
