It doesn’t seem to matter what Kevin Dineen does in trying to change the Panthers’ fortune. Nothing seems to work. Dineen has changed goalies, practice venues, offensive lines and defensive pairings. Even wearing his lucky green tie with embroidered shamrocks didn’t help things Saturday night, although for a bit it looked like it might. The Panthers fell into a 3-0 hole only to rally and tie the score in near-record time. Yet the visiting Islanders scored with seven minutes left and handed Florida its sixth consecutive loss with a 4-3 victory at BB&T Center. “I’ve had it almost a dozen years,” Dineen said, his dark green tie still knotted tight. “Unfortunately, my record took a little beating.” Saturday’s game was Florida’s last at home for some time as the Panthers, riding a season-long winless streak, embark on a season-long, five-game road trip with games against playoff challengers Carolina, the Rangers, Devils, Maple Leafs and these Islanders.
