BEDFORD — When it comes to cliches, a Game 7 brings no shortage. From “do or die,” to “most important game of the year,” to “this is why you play hockey,” they’re all hit on.
Another one you’ll hear is players talking of giving a “60 minute effort.” With the way the Eastern Conference finals has gone, maybe the Bruins should consider breaking it down even further. After winning Game 2 and losing Games 4 and 6 in the second period, perhaps they should view it more as bringing three 20-minute efforts. One period has made the difference too often in the series, and the Bruins know it.
“That’s been our biggest challenge all year, is to put three solid periods together each and every game,” Gregory Campbell  said Thursday. “Tomorrow night is going to be no different. We have to take the first period and play well in that. Whether we’re up or down, the game is not won in one period. We have to make sure that we’re playing well in all three periods.
“If it goes extra time, that’s fine. We have the confidence that we can win those games, and we’ll just have to make sure that we’re executing and competing and working as hard as we can.”
The Bruins held a 3-0 lead in Game 4 and a 2-1 lead in Game 6, both of which were held after one and were erased after two. If you take away the second period of Game 2 in which Tyler Seguin  had four points in a five-goal Bruins’ second period, the B’s would have just two second-period goals this series. That isn’t to say that the B’s have been dominated in second periods, as it speaks more to a point that applies to both teams. Leads aren’t safe, despite the fact that this was billed as being such a big goaltender’s duel. Any team can steal a game with one strong period, and the B’s see playing three good periods as a starting point for success.
“I think you want to play a consistent 60 minutes,” Chris Kelly  said, “and maybe that will be our focus for tomorrow night — coming out and playing all three periods.”
