From the Boston Herald:
"Look for the B’s to add at least one player, likely a forward. One name not mentioned much who’d fit the bill: Islanders forward Bill Guerin, an unrestricted free agent-to-be who was the prototypical Bruin during his too-brief time here (142 games, 69-60-129). He has 15-19-34 toatls in 54 games with the Islanders."
Guerin has a no trade clause. Weight we know will most likely not be traded due to his injury. Guerins family does not want to move. However, the Bruins are shooting for the Cup this year. It's completely up to Bill. My opinion, I don't think he'll waive his no-trade clause.
