I need to get in on this. Hiring an NHL coach is not, and will never be, the same thing has hiring someone in the normal business world. Quite frankly, sports is almost as far from the real world as you can get.
There is no way a team who currently has a coach, is going to start interviewing Mike Babcock. This day in age it is not possible to keep it a secret. Interviewing another coach would destroy the relationship with the current.
What was stated in the first quote is spot on. No way a team who currently has a coach with whom management is happy with, will interview Babcock. It's guaranteed to get out, and then your stuck looking for another coach.
I want to replace my accountant I can go out and interview a bunch and he's likely to never know. He'll keep on working just like he always does and there won't be any effect. If I'm not able to hire Joe Super Accountant life goes on and Larry the Above Average Accountant is none the wiser. I publically announce throughout the office that I'm interviewing Joe Super Accountant for Larry's job, than Larry's work is going to suffer, and guess what, he's probably going to quit or leave as soon as he can.
Hiring an NHL coach like Babcock is a very public event. It's not like replacing someone in the real world at all.
