Safety netting has been installed in all 30 NHL arenas, a response to the tragic death last season of 13-year-old Brittanie Cecil, who was struck by a puck while attending a Columbus Blue Jackets' game at Nationwide Arena. Reaction to the netting was not favorable during the preseason, with many fans complaining it obscured their sightlines. "This netting, I believe, is something that you will adjust to," NHL commissioner Gary Bettman said. "If you are a fan and you sit there fixated on the fact that you don't like the netting and you stare at the netting, it will be harder to adjust. If you sit back and relax and watch the game, within a minute you won't even know it's there." Even some of the networks that televise hockey games have complained about the netting. But Bettman made clear it's here to stay. "I remain certain that this was the right thing to do. Actually, it was the only thing to do, and we're going to continue to make sure that our clubs and our arenas get it right," he said.
