Staple: three BSTs set free

Today’s the qualifying-offer deadline, and Arthur Staple reports that the Islanders have tendered everybody they have to except Matt Mangene, Joey Diamond and Marc Cantin. They did tender Aaron Ness, Brett Gallant and Kevin Poulin.

Market opens tomorrow.

It’s also development-camp season — Isles’ roster to come — and along with Alex Vazzano’s trip to Ottawa, the Rangers announced over the weekend that New Canaan/Brunswick product Kevin Duane and Cheshire/Notre Dame-West Havener Luke Curadi (former RPI teammate of Ryan Haggerty, who’s obviously there as well) are at their camp this week.
