Apparently John Tortorella went to the Mike Keenan School for Hockey Coaches. I am sure that Tortorella has many excellent coaching qualities - nobody gets hired to be one of the 30 NHL coaches without having a lot going for them - but I wouldn't hire him as long as there was someone else who could skate and chew gum at the same time.
It is the difference between good human resource management and poor human resource management. How many successful managers in an office upbraid employees in front of others?
All this and so much more, inspired by Torts public criticism of John Grahame and Nikolai Khabibulin.
