This 2-0 victory over the Sabres at the Garden on Thursday night marked a return to order in the Rangers’ universe. First and foremost, Henrik Lundqvist — remember him? — was as close to peak form as he has been all season in recording the 29-save shutout during which he was in complete command, even if against an inferior foe. Though Cam Talbot’s emergence as a reliable understudy is a fine thing for the Blueshirts, the club’s persona is largely defined by their No. 1 goalie, who has struggled pretty much from the start of camp to establish the game everyone had become accustomed to over Lundqvist’s first eight NHL seasons. “It has been different,” The King told The Post after recording his first victory since his Oct. 16 shutout of the Capitals in Washington. “It’s been a challenge for me, for sure. “I have to keep working to turn things around.” The Rangers have sure turned things around since the season-opening five-game debacle out west in which the club allowed 25 goals in dropping four of its first five games. Since a return to normalcy, the Blueshirts have gone 4-3 in yielding a sum of 12 goals. They have allowed six goals in winning three of their last four to climb within one point of a playoff spot. “I think the guys are getting pretty confident with good chemistry as far where the puck is going,” Ryan McDonagh said. “We had five guys close to the puck all night, so we had good support, which is key. “We played a simple game. It was a good example of what we have to continue to do and it was good to see Hank playing the way we know he’s capable of.” The Rangers used speed to dominate the sad-sack Sabres, who have scored 22 goals in their 2-12-1 getaway. They wheeled through the neutral zone with ease, got the puck in deep, and smothered Buffalo’s attempts to clear the zone. By the end of the first period, the Rangers owned a 19-6 edge in shots and a whopping 34-10 advantage in attempts. The numbers mounted steadily for the Blueshirts until the final 10 minutes when the Sabres were able to test Lundqvist four or five times on one-and-dones the netminder turned aside.
