Four, though less than ideal, is more than last year, when Kline was the only one in attendance.
"A lot of people were like, [it's] competition," the 23-year-old Kline said. "No, I'm so happy about it. … I think the acceptance is growing. I always try to talk to the young girls when I'm out there doing women's games, 16, 17 [years old]. I'm like, 'You ever thought about reffing?' I always try to say it."
Though a position in the NHL as an official is beyond their grasp, at least at the moment, the NHL welcomed the women to take part in the combine as part of its mission to improve officiating at all levels, from midget to professional, Western Hockey League to ECHL, and in men's hockey and women's hockey.
This year the NHL actually had seven women lined up to attend. Three dropped out not long before the early August event, when Hockey Canada came calling, but four -- Kline, Vanessa Ley, Elizabeth Mantha and Joelle Ouellette -- arrived in Buffalo ready to soak in the lessons the NHL staff was there to provide.
