Defenseman Shea Weber’s 106 mph slapshot has broken bones and ripped through nets. But Weber’s wicked wrist shot is quite a weapon as well, as evidenced by the goal he scored Tuesday in the Predators’ 4-1 win over Buffalo. Taking a nice drop pass from Colin Wilson at the top of the faceoff circle, Weber zipped a perfectly placed wrist shot past the glove hand of Sabres goalie Jhonas Enroth. That goal put the Predators ahead 2-1 early in the second period and proved to be the difference-maker in the Predators’ victory. “Everybody thinks about the slapshot, but probably (Weber’s) wrist shot is, to me, his most effective shot,” Predators coach Barry Trotz said. “When he gets in there on top of the circles and snaps it off, it’s the most effective, and I think he can place it better. But he can loosen you up with a couple of slapshots, I know that.” Lively homecoming: It was a lively homecoming of sorts for Predators center Paul Gaustad, who played seven full seasons for Buffalo before he was traded to Nashville in 2012. Gaustad dropped the gloves with Buffalo forward Zenon Konopka midway through the second period, in retaliation for a low Konopka hit that upended Predators forward Viktor Stalberg. Gaustad wound up with a two-minute instigator minor and a 10-minute misconduct in addition to his five-minute fighting major. “I think he kind of took a little bit of liberties on Stalberg, but I give Konopka credit for standing in there,” Gaustad said. “It’s respectable for a guy to fight like that.
