IDK seems like a lot of unnecessary theatrics, especially in this market. Why bother? If anything, it is causing more unnecessary tension around the team and makes him look really incompetent as president... And he has certainly done enough of that in press conferences as it is. Would anyone really bat an eye if he just said "we decided to go in another direction"?
Sure, some may disagree with the decision, especially in regards to finding someone who will be as good/better than Dubas was, but he would be criticized if he extended Dubas too. If he had a good plan in place in terms of his replacement... I don't think anyone would really complain. Of course, the replacement will be compared to Dubas, as Dubas was to Lou, and there is uncertainty, but this is why Shanny gets paid big money and he should know all of this.
Now from Dubas' perspective, I guess he could have done the same thing: Just say he was not interested in coming back. But I think he wanted to continue running the Leafs, just not in the same fashion as before.
