NESN and the Bruins tonight will debut a new TV series, called "Behind the B," at 8:00pm ET. Thirteen episodes are slated to air during the '13-14 season. The Bruins allowed access to the team's locker room, exec boardroom and players' homes that will give fans a behind-the-scenes look at the inner workings of the organization (Bruins). Bruins President Cam Neely said, “I watched ‘24/7,’ my family was into it, my kids and my wife. And for me, I felt like, if my family is really interested in sitting down and watching this as a family, there are plenty more out there that are doing that. And then after an episode aired, you’d hear people talking about it, commenting on it, and even the casual fan tuned in to see what it was all about. It made me really think about how we could do something like this with our team and NESN. I really wanted to do some kind of show." He added, "Knowing that we would edit it ourselves, that was reassuring to anyone who might have not been comfortable at first about what might end up on air. That was extremely important, for them to know that nothing that would air to cause concern for anybody.” In Boston, Chad Finn noted all episodes but the premiere will run a half-hour, while actor Denis Leary, a "friend of Neely’s, narrates" (BOSTON GLOBE, 9/6).
