After opening the season with three straight wins, the Boston Bruins have hit a rough patch, losing four consecutive games. They will have a chance to halt that streak tonight when they face off against the Florida Panthers at TD Garden. The game will mark the return of former Bruins great Brad Marchand, who was traded to Florida last March. Marchand helped the Panthers win another Stanley Cup and spent 16 seasons wearing the black and gold. Tonight will be his first time back in Boston wearing a different uniform.
