Fluto article in the Globe today nails how I feel about the whole situation.

On Tuesday, Dougie Hamilton signed a six-year, $34.5 million extension with Calgary, his new team. Hamilton’s contract was not much richer than the Bruins’ initial offer, which was met with a shrug.
During a conference call, Hamilton declined to answer questions about why things went off the rails in Boston, but his actions indicate he wanted out. Of all the possible reasons, none is more likely than a 22-year-old player who grew weary of the heavy hand with which Claude Julien delivered his message.
Still, Julien’s teachings helped make Hamilton very rich.
Like all good coaches, Julien treated young players differently than he did veterans. It’s neither realistic nor prudent for a coach to issue corrections to Zdeno Chara and Hamilton in the same way. Coaches aren’t as strict with veterans because they acknowledge their mistakes and respond in a professional way. Coaches can’t be so sure with players on their entry-level contracts.
Teenagers and 20-somethings require firmness early. If they don’t learn to play with structure, they will float through their careers with bad habits tailing them until their deficiencies overshadow their skill set (see Phil Kessel, also not a Julien fan).
