Hmmm.....I guess I just have different experiences. As somebody who has been hired away from a current job by a competitor, you just don't talk about those negotiations or even your intentions until the deal is done and the job offer inked. There's way too many things that can upset the proverbial apple cart...not the least of which is your existing employer trying to negotiate with you to stay. That's a painful and almost always fruitless situation. So I don't take anything from Tulsky's or Rod's statements about Don's departure as anything but SOP.
Also, I listened to the entire podcast and don't recall Rod saying anything about him not liking Dundon's "negotiations". I do recall that he said he didn't like the results of not being able to keep guys he valued. And in the end, he closed that part of the conversation with a version of, "....but we all know it's a business".
I found this to actually be somewhat humorous and think that's how Rod meant it. I believe you have to pair that statement with GMET's statement about the number of phone calls he gets in a day....with a couple of dozen of them being from the owner (I'm paraphrasing here). They both know that Tom Dundon is deeply involved with the team. In the past, I believe it was Rod who said that Tom came in not knowing a great deal about hockey but how impressive it was how he had learned so much in a short period of time (that might have actually been from Don W.).
Tom Dundon might be an asshole. He might be a prick to work for. He might be a bastard to negotiate with. But he clearly loves this team and wants it to be successful. If he's doing things to harm the team, I have faith that will be communicated and, if he still wants to maintain success, he'll modify his behavior. Currently, I don't see any of these negotiations as having truly hurt the team (we can speculate about Guentzel's contract, but there's been no actual reporting other than speculative rumors). In the end, I like that a maverick owns our team, shake's up the NHL old boys network, and ultimately is invested in putting the best team possible on the ice.
