I am not so sure they would. Anyone who has a source and knows something is probably a good enough insider to not want to piss the NHL off. One word of this from a guy like Friedman, Mackenzie, Dredger, etc and the Cup finals become secondary to most hockey fans. (other then fans of those teams) All the attention and talk will go right to Ottawa and because nothing can be announced until after the playoffs are over it will linger and be a consistent distraction. The top insiders know when to release stuff and what to release. Staying to much or saying at the wrong time hurts their ability to get more info. For example Friedman (i believe it was him) was talking a while back about a high end drafted prospect struggling in the CHL due to a video game addiction. He never said who or gave enough hints to figure it out as giving the name looks bad on him from of point of view of the people giving the info. Next time maybe he does not get any info and has nothing to say.
Ottawa media members could say something but what would they gain? They get the story but piss of the NHL and the new owners doing it. Good luck getting inside info or special treatment after that.
It may or may not be happening. Not sure what i believe but i don't think we will be getting any insider info on it during the playoffs (especially the cup finals) if it is happening.
Your rationale makes perfect sense for the hockey insiders, but this is not where any such leak would be given first. Think of all the lawyers, clerks, accountants, bankers etc that would be involved in a deal like this. It would first be leaked to financial insiders at the Globe or someone like that, then maybe hockey guys after that. There would be articles appearing in the financial circles first.
I don't buy this story even a little bit, not a chance could you keep wraps on a deal this big for months. An idiot leaf fan tweets something random and the place explodes, people can't be this gullible. I get that everyone wants it to be true but simmer down.
Of course there are still interested parties, it will be a great product downtown. Melnyk will only sell now if he gets an offer worth quite a bit more than current market value, otherwise he waits a while longer. It could happen in the near future but it hasn't happened yet, we'll know when it does
