So much focus of the Boston Bruins’ Third Annual Development Camp this week in Wilmington, Mass., was on the draft picks that it was easy to forget that of the 25 attendees there were many who were invited as a first step toward possibly joining the Boston organization sometime in the future.

In the case of Scott Campbell, who was coming off a 30-point sophomore season at UMass-Lowell, the development camp provided a great opportunity for self-asessement.

“It was an awesome experience, for starts. But also, as the coaches and the staff have stressed all week, it helps us kind of identify ourselves as a player and learn more about ourselves,” the 6-foot-2, 210-pound forward said yesterday after the last day of camp. “I think everybody that came in here learned about some of the areas that they need to improve on in their game, including myself.”

No doubt the Bruins will keep close tabs on Campbell as he continues to grow with the River Hawks. And he’ll continue to put some of his lessons from the camp to use in the future.

“It was just an accumulation of a lot of little things — just little areas of my game that I need to improve on. And just punctuality and a lot of life skills too when I came here. So overall it was just a benefit to me as a hockey player and as a person as well,” said Campbell, 23, who will go home and work out until returning to the Bay State later this summer.

Six-foot, 185-pound defenseman Mark Isherwood, who’s 20, enjoyed his experience over the last five days.

“There were a lot of good players that played here and it’s my first camp and it’s good to get one under your belt and know what to expect for your next one. It was good. I’ll take a lot out of it and go back home and work that much harder,” he said.

Isherwood will be joining Medicine Hat for his fifth Western Hockey League later this season. A right-handed shot, he could also someday get his name on a deal with the Bruins. But for now, all he’ll take back to British Columbia with him is the main lesson he learned during camp.

“It’s a different level. You’ve got to work that much harder and that much better shape,” he said.
