Settling on a second-line right wing is one of the few question marks for last season’s Stanley Cup finalists.

The 20-year-old Keyser has been impressive so far during Boston’s preseason.

Boston returns with essentially the same roster that made it to Game 7 of the Stanley Cup finals last year.

The young forward played better than expected last season, and might be slotted in alongside David Krejci and Jake DeBrusk.

The defenseman played well as a fill-in for injured players last year, but might be hard-pressed to get a roster spot this season.

On the eve of training camp, Boston rewards Cassidy for guiding the team to the Stanley Cup finals.

Boston had a home crowd and early scoring opportunities, but couldn’t take advantage in a 4-1 loss to the Stanley Cup champion St. Louis Blues.

St. Louis, which was in last place in the NHL in early January, caps its remarkable comeback with a 4-1 win at Boston.

The Bruins and Blues are down to one game for the Stanley Cup, and St. Louis carries a 9-3 playoff record on the road into the deciding game.

Boston stormed to a win in Game 6 and is playing at home with the Cup on the line.
