It's so weird I'm not sure if I believe it. Or at least whether it's 100% accurate.
But let's say it is: in what universe do they negotiate a deal that doesn't include them getting to announce they've parted ways? That would be insane. That would be gross negligence. (Which, yes, this entire affair has been.) The money, the roster spot, the cap hit all pale in comparison to the reputational damage of being associated with him and having listed as being part of the Bruins organization.
This story doesn't pass the smell test, so I'm not really getting worked up either way until we know more.
If though, we find out this a planted story to make them look better because they didn't want to lose the 200k cap space on the main roster then I'm going Defcon -37.
