There certainly was a lot came out after the playoffs. During however you saw nice fluff pieces like this:
Seguin Turned To Claude Julien For Help During Slump
As for how Bergeron addressed Seguin, I may have missed something but both his and Chiarelli's comments seemed a far bit less worse then how they seem to be have been made out.
Maybe it was just off ice issues, but I look back to the Milan Lucic "do you know who I am" incident, and the stories about him and his now wife outside of bars post cup and see the Bruins have quite the tolerance for that kind of crap. Common sense dictates they'd have to dealing with 20 somethings, whom regardless of occupation are mostly braindead (I was at that age as are most).
This screams hockey trade to me, and hey, if it works it works. Things are getting blown way out of proportion in regards to the off ice antics, and haven't even been hinted at by anyone not named "source", in fact refuted by our own GM in Chiarelli ("But when I said earlier about focus, just about little things, about preparing to play. It was nothing about extracurricular activities.â€)
The latest idiotic Horton/Seguin angle is more proof of that same insanity.
It is what it is, a trade that could work out for Boston short term, long term, or no term. Abusing the player publicly as he leaves may make everyone feel like the risk is far far less, but in reality it only makes the people slandering the player look bad. In the case where it's all the media and much of the fanbase... well it's things like that that can alter players perceptions of an organization.
