Very unprofessional for Hartnell to make such public comments. The Flyers are in a fight for a playoff spot and this nonsense is exactly the type of distraction neither Hartnell, nor the team needs right now.
You keep your private life private, period. Whatever the circumstances of his marriage were, it should have only been between those 2 people and it should have never been made public. Hartnell would be wise to forgive and try to move on with dignity. You don't get anywhere in life directing venom at people or trying to publicly humiliate. It just makes you look bad. Hartnell and Richards both have some maturing to do.
