WILMINGTON – The Bruins have completed their first on-ice session of their annual development camp at Ristuccia Arena.

Of the group, Dougie Hamilton is the closest at cracking the NHL roster. Hamilton checked in at 6-foot-5, 193 pounds. Hamilton could top 200 pounds once he reports for training camp in September.

“Doug had a really, really good year,” said assistant GM Don Sweeney. “He was a dominant player at that level. He went back and worked on a lot of things we had addressed with him in rounding out his game and decision-making. He’s such an athletic player to begin with, at that size and how he moves. Overall, he became a dominant player at that level. He’s ready for the next step and the next challenge.”

* Jared Knight and Torey Krug project to be at the next level under Hamilton. Both players should start 2012-13 in Providence. Knight has NHL size and tenacity. Sweeney noted that Knight took advantage of his size in junior, and might not be able to do the same as a professional. Krug appeared in two NHL games last year.

* Malcolm Subban spent his first day in Bruins gear. Subban, the No. 24 pick of the 2012 draft, relies on athleticism and competitiveness to make his stops. Sweeney mentioned Subban’s explosiveness in moving from side to side.

* Alexander Khokhlachev could be headed to the KHL next season. Khokhlachev has played for Windsor of the OHL. Regardless of whether he plays in the KHL or returns to junior next year, the skilled forward will report to Bruins camp in the fall.
