Shea Weber’s 100th career goal — his first of the season — seemed so un-Weber-like. From the Ducks’ blue line, the Predators’ captain, who is known for his 100 mph slapshots, flicked a high, harmless-looking wrist shot on the Anaheim net. It bounced off Ducks defenseman Luca Sbisa and past goaltender Viktor Fasth. Sbisa had forward Gabriel Bourque tied up in front of the net, and Weber thought Bourque deflected the shot. “I honestly thought Bourque scored it,” Weber said. “It looked like he tipped it, so I was excited that we got the goal, I was happy for Bourque, but it ended up hitting their defenseman.” The goal was 15 games in the making for Weber, who has struggled to find his offensive footing this season. He now has the one goal and two assists. He also fired a slap shot off the crossbar at the start of the third period.
