It was entirely predictable that David Warsofsky was paired with Kevan Miller on the first day of on-ice sessions at Bruins training camp at Ristuccia Arena. The 24-year-old defenseman was essentially skating in the spot that might have otherwise been occupied by fellow puck-moving offensive defenseman Torey Krug, but Krug is instead temporarily out of the camp picture while waiting for a suitable contract from the Bruins. Both are on the smaller side in stature, both play on the left side and both have high risk/high reward style built into their offensive skill games. All of those qualities make Warsofsky pretty good insurance for the Bruins if negotiations go south with Krug as they sit $750,000 apart on a potential one year bridge deal. The Marshfield native is happy to step into that opportunity with his hometown team, and try to win an NHL spot in this camp at a key point in his pro career. “Getting a couple of games last year and kind of proving myself at this level definitely gives me a lot of confidence going into this camp,” said Warsofsky. “Something is going to happen with the defensemen, but nobody really knows right now. Until that time I’m focusing on myself, and controlling what I can control. “Obviously the situation with Torey will get resolved at one point or another. We’re the same type of players, but right now I’m just focused on myself and the situation will take care of itself. Like everyone, I’m on social media and see things, but the more I can not pay attention to it [the better]. I just need to go out and practice the way I know I can play, and prove myself in the games.” But Warsofsky still isn’t viewed as Krug’s equal after the Bruins defenseman finished fourth among Calder Trophy voting last season while posting 14 goals and 40 points as a first year player. Warsofsky had six goals and 32 points in 56 games for the Providence Bruins last season, and he added one beauty of a goal when called up to Boston last season.
