The Bruins have signed center Patrice Bergeron to a three-year extension. The deal, worth $15 million, will keep the 25-year-old forward in Boston through the 2013-14 season. "I knew it was going to get done, because at the end of the day I was the one who was going to say yes no matter what," Bergeron said Friday. "I just feel comfortable in Boston, it's my home now. I just wanted to stay in Boston and I think [general manger] Peter [Chiarelli] and the Bruins knew it all along."
