NCAA Hockey Coaches rarely get fired. They tend to stick around for decades, because it's a great job by hockey coaching standards ... you get paid well, you have very little travel, you choose your own roster, and there is zero roster turnover in-season so you can actually develop a team.
What happens more often is that a player underachieves and is not offered a scholarship the next season. Once a player and the team sign their scholarship agreement, it is only good for one season. That is not a well-known fact ... NCAA scholarships are year-to-year.
