Sometimes you set expectations high, and you consistently put up good regular season numbers. (What is it? The best win% since x year now?)
Bruins don't set a record this past season, Bruins don't look outright dominant most of the season. And a first round exit happens. Sometimes you lose because you choke. Badly. It's happened more times than I'd care to admit, why? Because we were in positions to win and didn't.
Anyways, no one was complaining at deadline because he was on the right side of the storyline at the time. Now he's on the wrong side again.
Sweeney isn't the worse GM, and the loss itself, not his fault. But the situation the team is in now, is his 100%.
