Hockey fans may have noticed that teams are making coaching changes at an insane rate. The actual rate may be even more crazy than you previously imagined:
Crazy stat: 13 of the NHL's 30 coaches have been hired since the 2013 off-season. Nearly half the league in a year.

Mirtle also points out that only six coaches have lasted longer than three seasons in their current role.
