Comebacks have been the order of the day during the first round of the Stanley Cup Playoffs. All three games Wednesday saw teams overcome deficits to even its series at 2-2. The eight games in which the winning team has overcome a deficit of two or more goals match the total for the entire 2013 postseason."If you're watching the game in the first period at home and you go to put your kids to bed or something and go read them a book, and then come down for the third, there's two different games going on," Islanders defenseman Matt Carkner said Thursday while visiting the NHL offices. "The momentum swings and just the all-out intensity is pretty cool to see. I think it's great for the fans to know either team has a chance. That's the way it's going to be for a long time."
