07:32 AM ET 07.05 | For months, there were whispers about polarizing Tyler Seguin, who on Thursday was shipped to Dallas. Those sources clearly were onto something, because the Bruins yesterday made the decision to part ways with the No. 2 overall pick in the 2010 draft, who they feel is headed for trouble with his nightlife pursuits. ... Multiple sources said the 21-year-old Seguin crossed the line this season with reckless partying. It apparently got so bad that during the playoffs, the Bruins ordered Seguin to live in a hotel, where a guard was hired to make sure he stayed in his room. But [Peter Chiarelli] repeatedly defended Seguin, calling him "a good kid and a terrific player" and "a tremendous package of speed and skill."
