The Boston Bruins suffered their second consecutive loss in their series to the Buffalo Sabres 6-1 in Game 4 on Sunday afternoon at TD Garden to fall behind in the series 3-1.  Throughout the series, Buffalo has not been able to get on the board in the first period.  That was the opposite in Game 4.  The Sabres tacked four goals onto the board in the opening frame to take a 4-0 lead.  The first goal of the afternoon came at 4:17 by Sabres center Peyton Krebs off of a Bruins turnover. A little under three minutes later at 7:10, right winger Josh Doan found the back of the net off another turnover by Boston to make things 2-0.  Left winger Zach Benson got in on the action and extended Buffalo’s lead 3-0 at 9:15 while defenseman Bowen Byram added his third goal of the series to the board at 14:24 to make it 4-0.…
